Physics Question, Please Help! ASAP Thank you?
you have arrived at the final accident scene of the day. two cars of equal mass (2,00 kg each) were involved in a head on accident at a four was stop intersection. here is what you know: - car 1 started at rest and coasted toward the intersection from the top of a 50 meter hill - car 2 was on a flat stretch of road at the bottom of the hill in front of car 1 - at the bottom of the hill, before braking, car 1 was going 30 m/s and car 2 was going 20 m/s - from the skid marks on the road you can see that car 1 applied force on its brakes for 5 second, 125 meters before the stop sign where it came to a stop. - there were no skid marks left by car 2. the collision occurred at the stop sign. where car 1 had stopped. after the collision, car 2 came to stop. car 1's final velocity is unknown 1. what was the potential energy of each car at the beginning of the problem? 2. what was the kinetic energy of each car while it was traveling at its maximum speed? 3. how much energy did car 1 "lose" from the top to the bottom of the hill, before it began braking? what happened to this lost energy? 4. how much force did car 1 apply to the brakes to stop?
HELP ASAP:::: A car moving at 8.5 m/s crashes into a tree and stops in 0.32 s.?
A car moving at 8.5 m/s crashes into a tree and stops in 0.32 s. v = 8.5 m/s t = 0.32 s m = 78.5 kg What would the final velocity be, in meters per second, if the car with the 78.5-kg passenger had collided with (and stuck to) a car that has a mass equal to and is traveling in the opposite direction and at the same speed?
Need help asap! Cars #1 and #2 are sliding across a horizontal frictionless surface?
Cars #1 and #2 are sliding across a horizontal frictionless surface. The cars are equipped with a coupling arrangement similar to the one on railroad cars. Car #1 overtakes car #2 and they have a totally inelastic collision and become coupled together. You know the mass of each car; m1 = 17.0 kg and m2 = 44.0 kg. In addition, you are provided with the momentum of car #1 before (p=100N.s), and after the collision (p=40N.s). Determine the velocity of car #2 before the collision. Okay, I just cant seem to get this one right. I know P1+P2=P` and that I have P1 and P` (or P2?) and can use that to calculate the other parts but I keep getting wrong answer. Online homework due at 1:00pm Central standard time.

Ok so I got into a very minor wreck NEED HELP ASAP PLEASE!?
Ok so I got into a very minor wreck. I was coming out of the alley trying to make a left turn and this lady was coming straight driving on the main road and i didnt see her so I hit her side bumper a little bit barely at all. It was my fault because it was her right of way however she is making a huge deal out of it. Her side bumper has a very minor scratch and its not even dented at all and she is asking $500 to get it repaired and I know it doesnt cost that much because its extremely minor where you cant even see it. Honestly I think she is just trying to get money out of this, however I am not an expert in cars and repairing them so I figured someone on here who is an expert can help me get an estimate of how much this repair will cost? I am posting links that lead to the pictures of the side bumper on her car. I took pictures from every angle including the side itself, the front, and the very far side of it. If anyone can help me with this I will appreciate it a lot! THANKS! :) P.S. I do have insurance but I figured negotiating would be better than to file a claim over such a minor thing.

Physics problem! Need help ASAP!?
The instructor is trying to trip you up in the units. Convert everything to meters/second and then find the KE 1000m/hr * 1hr/3600s = 5/18 m/s 20e9mm/r * 20e6m/yr * 1yr/31,556,926s = 0.6338m/s KE = ½m1V1² + ½m2V2² = ½*0.05*(5/18)² +½*0.012*(0.6338)² = 4.339e-3 J <----- a)
Need help with a physics problem ASAP!!!?
Car A hits car B (initially at rest and of equal mass) from behind while going 36m/s . Immediately after the collision, car B moves forward at 26 m/s and car A is at rest. What fraction of the initial kinetic energy is lost in the collision? Thanks alot
I need help with a multiple choice Economics question!!! 11 points ASAP!! NEED IT NOW?
When Joe didn't have car insurance, he drove very cautiously because he knew he would have to pay for any damage to his car. Now that he has car insurance, he drives like a maniac because he knows that even if he gets into an accident, his insurance will cover it The economic problem in this story is known as: A. Moral hazard B. Screening C. Adverse selection D. Signaling
