A0.143 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.900 m/s. it has a head-on collision with a 0.298 kg glider that is moving to the left with a speed of 2.25 m/s. suppose the collision is elastic. find the magnitude of the final velocity of the 0.143kg glider. find the magnitude of the final velocity of the 0.298kg glider.

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?
