Two hard, steel carts collide head-on and then ricochet off each other in opposite directions on a frictionless surface. Cart A has a mass of 0.350 kg and an initial velocity of 2 m/s. Cart B has a mass of 0.500 kg and an initial velocity of −0.500 m/s. After the collision, cart A recoils with a velocity of −4 m/s. What is the final velocity of cart B?

Two carts with masses of 4.40 kg and 2.68 kg move toward each other on a frictionless track with speeds of 5.14 m/s and 3.04 m/s respectively. The carts stick together after colliding head-on. Find the final speed.

A body of mass 4 kg moving at a speed of 3 m/s collides with another body of mass 2 kg moving at 2 m/s in the opposite direction. If the collision is perfectly inelastic, find the velocity of the two bodies after the collision.*1 point1.33 m/s2.34 m/s3.22 m/s4.00 m/s

A ball A collides head-on with another ballB of equal mass. Assuming that ball B is atrest and their collision is elastic, determinethe final velocities of these balls
