Momentum and CollisionHard
Question
A ball hits floor and rebounds after an inelastic collision is the same as that just before the collision
Options
A.the momentum of the ball just after the collision is the same as the just before the collision
B.the mechanical energy of the ball remains the same in the collision
C.the total momentum of the ball and the earth is conserved
D.the total energy of the ball and the earth is conserved
Solution
The ball & the earth from a system and no external force acts it. Hence total momentum remains constant.
