STANDARD Physics Coefficient of Restitution MCQ Question
A ball of mass M falls from a height h on a floor and its coefficient of restitution is e. The height attained by the ball after two rebounds is
e²h
eh²
e⁴h
h / e⁴
Correct Answer
Detailed Explanation
The rebound height after each collision is reduced by a factor of e. After two rebounds, the height is e⁴h, as the height is multiplied by e² for each rebound.
