Question
1). Two carts approach each other, collide, and stick together after the collision. This is an example of what type of collision:
perfectly elastic collision
inelastic collision
2). Two carts collide and bounce off each other. If there are no external forces acting on the system, which of the following is true:
both the total kinetic energy and the total momentum can change during the collision
3). A cart with mass 0.21 kg and velocity 0.81 m/s collides on an air-track with a cart with mass 0.26 kg and velocity -0.25 m/s. What is the final velocity (in m/s) of the two carts if they stick together?
elastic collisionExplanation / Answer
perfectly inelastic collision
The total kinetic energy can change during the collision but the total momentum of the carts must be the same before and after the collision
