Question

Two small carts are set up on a horizontal track. Cart A (mass 0.6 kg ) sits at rest. Cart B (mass 1.3 kg ) moves to the right with a speed of 3 m/s , colliding with cart A.

A) If the collision is perfectly elastic, what is the speed of cart A after the collision?

B) If the collision is perfectly elastic, what's the speed of cart B after the collision?

C) If the collision is perfectly inelastic, what is the speed of cart A after the collision?

D) If the collision is perfectly inelastic, what is the speed of cart B after the collision?

E) If cart A's speed after the collision is 2.87 m/s  instead, what kind of collision was it?

-Perfectly elastic.

-Perfectly inelastic.

-Somewhere between perfectly elastic and perfectly inelastic.

F) If cart A's speed after the collision is 2.87 m/s instead, what is the speed of cart B after the collision?
