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.
(True, False, greater than, equal to, less than)
Immediately after colliding with m2, the mass m1 stops and has zero velocity.
The maximum energy stored in the spring is ...... the initial energy of m1.
Immediately after the collision, the momentum of m2 is ....... the initial momentum of m1.
Immediately after the collision, the energy of m2 is ...... the initial energy of m1.
Explanation / Answer
Immediately after colliding with m2, the mass m1 stops and has zero velocity. False. (It will move to the Left)
The maximum energy stored in the spring is Less than the initial energy of m1. (Energy Conservation)
Immediately after the collision, the momentum of m2 is Greater than the initial momentum of m1. ( Because m1 will move in negative direction and will have negative momentum, as momentum is conserved so m2 will have greater momentum )
Immediately after the collision, the energy of m2 is Less than the initial energy of m1. (Energy Conservation)
Immediately after the collision, the energy of m2 is the initial energy of m1.
