You are a witness in a court case involving a car accident. The accident involved car A of mass which crashed into stationary car B of mass . The driver of car A applied his brakes before he crashed into car B. After the collision, car A slid while car B slid 3. The coefficient of kinetic friction between the locked wheels and the road was measured to be . What was the velocity of car A before hitting the brakes?

A car with mass and initial velocity strikes a car of mass , which is at rest. If the two cars stick together after the collision, what is the final velocity?

A car traveling at collides with another car that is at rest. The two bumpers lock and the cars move forward together. What is their final velocity?

Hockey puck A () travels with a velocity of to the right when it collides with hockey puck B (), which was originally at rest. After the collision, puck A is stationary. Assume no external forces are in play and that the momentum of the pucks are conserved. What is the final velocity of puck B after the collision?

A sports car collides into the rear end of SUV stopped at a red light. The bumper lock, the brakes lock and the two cars skid forward before coming to a stop. The police officer, knowing the coefficient of kinetic friction between the tires and the road is about . He calculates the speed of the sports car at impact. What was that speed?

Two bumper cars at an amusement park collide elastically as one approaches the other directly from the rear. The car in front (CarA) has a mass of and the car behind it (CarB) has a mass of . The car in front was traveling at while the car behind hit him with a velocity of . What are their final velocities after the collision?

Which of these would NOT be an example of an inelastic collision?
