The mass m 1 enters from the left with velocity v 0 and strikes a mass m 2 > m 1

Question

The mass m1 enters from the left with velocity v0 and strikes a mass m2 > m1 which is initially at rest. The collision between the blocks is perfectly elastic. The mass m2 then compresses the spring an amount x.

Immediately after colliding with m2, the mass m1 moves to the left.
Immediately after the collision, the momentum of m2 is ....... the initial momentum of m1.
The maximum energy stored in the spring is ...... the initial energy of m1.
Immediately after the collision, the energy of m2 is ...... the initial energy of m1.

ANSWERS ARE EITHER, TRUE, FALSE, EQUAL TO, GREATER THAN OR LESS THAN***

Explanation / Answer

Immediately after the collision, the momentum of m2 is greater than the initial momentum of m1.
The maximum energy stored in the spring is less than the initial energy of m1.
Immediately after the collision, the energy of m2 is less than the initial energy of m1.
