Mathematics · System of Particles and Rotational Motion
A ball falls freely from rest onto a hard horizontal floor and repeatedly bounces. If the velocity of the ball just before the first bounce is 7 m/s and the coefficient of restitution is 0.75, the total distance traveled by the ball before it comes to rest is (take acceleration due to gravity g = 10 m/s2):
- 111.75 m
- 28.75 m✓
- 39.75 m
- 410.75 m
Correct answer
8.75 m
