Momentum and CollisionHard
Question
A ball hits the floor and rebounds after an inelastic collision. In this case
Options
A.the momentum of the ball just after the collision is the same as that just before the collision
B.the mechanical energy of the ball remains same in the collision
C.the total momentum of the ball and earth is conserved
D.the total mechanical energy of the ball and the earth is conserved.
Solution
In an inelastic collision only moment of the system may remains conserved. Some energy can be lost in the form of heat, sound etc.
∴ Correct option is (c).
∴ Correct option is (c).
