Is it ok to buy "Loss of use - car rental" for insurance policy without buying collision?
Q. And if my car insurance policy has both: loss of use and collision, and if I was involved in an accident, is it ok for me to use car rental without claiming collision? Thanks

A. You can purchase rental reimbursement coverage without having collision. If you are involved in an accident, you would be covered for the rental even if you wouldn't be covered for the damages. If you have collision coverage and rental, you could only use the rental coverage if you were involved in a covered loss (an accident). In other words, if your car breaks down or if you just need a rental for the weekend, the rental coverage cannot be used. Edit: In reference to the answer below, I work as a claims rep for an insurance company (one of the largest insurance companies in the US). Although it's rare, I have handled claims for rental only because the insured did not have collision coverage. Rental reimbursement is purchased separately… [cont.]

Can someone explain loss of momentum in a collision lab?
Q. Ball 1 was rolled from rest down a ramp to hit a stationary ball 2 at the bottom of the ramp. When I calculated the momentum before and the momentum after the collision, I came up with a 24% difference. When I calculated kinetic energy before and after the collision, however, the result was only a .04% error. What could have caused an error in the momentum but not the energy?
Asked by Gina R - Wed Dec 2 17:20:56 2009 - - 1 Answers - 0 Comments
A. You should only account for the horizontal component of the momentum. The vertical is being "absorbed" by the table into the earth.

Expressing the kinetic energy in terms of momentum that the fractional loss during the collision is M/(m+M)?
Q. Expressing the kinetic energy in terms of momentum [i.e., K = 1/2mv2 = p2/(2m)], prove using symbols, not umbers, that the fractional loss during the collision is equal to M/(m + M).
Asked by freeman - Mon Apr 19 03:07:12 2010 - - 2 Answers - 0 Comments
A. Consider a body of mass m initially at speed vi colliding inelastically with an initially stationary body of mass M. You can always define this to be true with careful selection of reference frames. Initial momentum: p = m*vi Final momentum: p = (M + m)*vf These are equal because momentum is conserved: m*vi = (M + m)*vf solve for vf: vf = vi*m/(M + m) Now let's talk about kinetic energy: KEi = 1/2*m*vi^2 KEf = 1/2*(M + m)*vf^2 Substitute: KEf = 1/2*(M + m)*(vi*m/(M + m))^2 Simplify: KEf = 1/2 * m^2*vi^2/(M+m) Fractional change in KE: (KEi - KEf)/KEi Substitute: ((1/2*m*vi^2) - (1/2 * m^2*vi^2/(M+m)) )/(1/2*m*vi^2) Cancel vi: ((1/2*m) - (1/2 * m^2/(M+m)))/(1/2*m) Cancel 1/2: (m - m^2/(M+m) )/m Divide through by m: 1 - m/(M+m) … [cont.]

Physics: loss of kinetic energy, inelastic collision?
Q. A 2 kg ball moving east with a speed of 3 m/s collides and sticks to another ball of mass 3 kg moving west with a speed of 4 m/s. I already found the velocity of the combined masses just after the collision and it is 1.2 m/s. What is the loss in kinetic energy of the 2 masses due to the collision? The answer was given as 32.6 J, I came up with 29.4 (final KE of 3.6 J, initial KE of 33 J). I need to know what I did wrong, or if the given answer is wrong.

However, given today's economy, you might be able to find one willing to work with you.

Do both parties get a point on their DMV record for at-fault accident? Does the court simply decide 50/50, is that possible? Or are both parties spared of at-fault and simply required to handle their own financial losses? Only answer if you are 100% certain of legal affairs. Thank you.

It also depends on how long it has been since your accident (the more recent the injury the better for you). Without testing, no one here will be able to tell you what is wrong exactly. You need to go to a doctor - preferably your family doctor, but any will do - and get a referral to see a neurologist right away!!! This is very serious!!!

Are there any independent companies that will sell short-term collision/damage/loss insurance, so I don't have to buy it from the vendor? I've been buying low-cost CDW for car rentals this way, but the company I use doesn't cover truck rentals and I can't find another company that will do it. Our liability insurance for our car will provide coverage, but not for any damage that happens to the truck we will be driving.

A. Not that I'm aware of. You must buy the insurance from the rental company; ordinary auto insurance does not extend to rented trucks. Nor does the insurance coverage provided by credit cards. One very important thing to keep in mind: The insurance from the rental place does NOT cover the top of the truck. Ever! If you go under a low bridge or other overhang and strike it with the top of the truck you will be personally responsible for all damages. No insurance company covers the top of the truck's body.

Q. A dog jumps into the interior of a stationary ice boat is moving at 32km/h when he enters the boat, and his landing onto the bost can be regarded as a collision. The dog's mass is 14 kg and thoat of rhe bost plus boater is 160kg. You can assume all of the motion is horizontal. a) Assuming that the ice surface is frictionless, what is the veoliduty of the boat after the collision? b) What is the ratio of the kinetic energy loss to the initail kinetic energy? c) Kinetic energy is lost. Where did it go?

Central nervous damage from automobile collision....?
Q. Only those with knowledge in the medical field should try to answer this. I have a relative who is a very healthy, young but who suffers from depression at times. When he was younger he had been in an auto collision where by the grace of god he was not killed or paralyzed but something more sutbly devastating happend to him. He never brought this to the attention of anyone and even he dismissed it, but I believe the incident left him with a kind of tremor on his body, noticably from involuntary finger movements and shaking from his arms and trembling in neck in a certain position. It is not a complete loss of motor control but it is very apparent if you were to notice very carefully there is something terribly wrong He is a very kind,… [cont.]

A. Hi. Something potentially very serious is happening with your relative's CNS. It would be very wise to seek an evaluation with a good Neurologist. It may also help to read a copy of "The Better Brain Book" by David Perlmutter, M.D. Dr. Perlmutter is a Neurologist and leading specialist in brain injury. He recently received the Linus Pauling Award in Medicine for his cutting-edge work. The book is available at Amazon.com. It may offer lots of useful information, but again, I strongly recommend a thorough evaluation by a competent Neurologist. Best wishes and good luck.

How do I properly dispose of a car seat that was involved in a wreck? ?
Q. The car was involved in a 4 car crash and the car was a total loss. The car seat appears to be perfect, but I know you aren't supposed to use them after a collision, especially being in a totaled car.

A. Do the same as you would for a bicycle or motorcycle helmet...make sure that it is completely destroyed. You're right...even though it appears it sustained little or no damage, it should never be used again. It's the same with helmets...one wreck and even if the helmet doesn't have a scratch on it, it should be destroyed...because you have no way of knowing (until it's too late) that it will perform as it should. Seat belts are the same way...one accident and they should be removed and replaced. It doesn't matter if you take it to a junk yard, have it crunched in a garbage truck or chop it up with an axe...just make sure that it is completely unusable...to prevent another person from mistakenly believing that it will work fine.

Negotiating Nationwide Collision Claim on '99 Hyundai Tiburon?
Q. I live in Pennsylvania, and have Collision on my Nationwide insurance policy. with a $500.00 Deductible. My 1999 Hyundai Tiburon was declared a total loss and I was at fault. It had about 104400 miles, A/C, and a rear spoiler, an aftermarket cd player that I had removed to use in another car. I apparently didn't have a rental car option on my policy, so I am paying for that out of pocket. Before the collision-car was in good shape a few scratches and dents, nothing major, inside was clean, no damaged interior-car was well taken care of. Had some "sunburn", but the car had it when I bought it. Car was purchased about a year ago- for $4500 from a dealer. My insurance adjuster called me today, and gave me a total claim amount of $3100,… [cont.]

A. The price that they are offering is fair, based on current market conditions. These cars are not bringing a whole lot on the market these days. In fact, if I had one on the lot and was able to get $3100 for it, I would be doing the "snoopy happy dance" Sorry
