Work Energy And Power Question 60
Question: A ball hits the floor and rebounds after inelastic collision. In this case [IIT 1986]
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 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
Show Answer
Answer:
Correct Answer: C
Solution:
By the conservation of momentum in the absence of external force total momentum of the system (ball + earth) remains constant.
