Describe the energy transfers that occur as the cart moves along the track.
At each of the identified points, how was kinetic energy transferred to potential energy, and vice versa?
What happens to the total energy of the cart as it moves along the track? Why?
How is the principle of conservation of energy applied in this situation?

What was the kinetic energy of each cart before and after the collision?
What happens to the total energy of the system, now including both carts, as a result of the inelastic collision?
Describe how the principle of conservation of energy is applied in this situation.

Describe the amount of work due to friction and frictional force exerted to stop both carts over 20 meters.

Describe the energy transfers that occur as the cart is brought to a stop.
