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.
True, False, greater than, equal to, less than :
1. Immediately after colliding with m2, the mass m1 stops and has zero velocity.
2. Immediately after the collision, the momentum of m2 is the initial momentum of m1.
3. The maximum energy stored in the spring is the initial energy of m1.
4. Immediately after the collision, the energy of m2 is the initial energy of m1.
