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.

ANSWER WITH: TRUE/FALSE, GREATER THAN, EQUAL TO, OR LESS THAN

1) The maximum energy stored in the spring is ...... the initial energy of m1

2) Immediately after colliding with m2 , the mass m1 moves to the left.

3) Immediately after the collision, the momentum of m2 is ....... the initial momentum of m1 .

4) Immediately after the collision, the energy of m2 is ...... the initial energy of m1 .

Explanation / Answer

1)
Less than (because of conservation of energy)

2) True

3)
less than (m1v1=m1v1'+m2v2'/initial momentum of m1=final momentum of m1 + final momentum of m2)

4)
(assuming you're talking about kinetic energy) less than (before collision: Et=Ek1, after collision: Et=Ek1' + Ek2)
