The coefficient of restitution for a particular ball is 0.45. If he ball hits a surface traveling at 100 m/s its rebound speed will be A) 100 m/s B) 90 m/s C) 45 m/s D) 45 m/s²

Question

Quizplus · Accepted Answer

The coefficient of restitution is defined as the ratio of the final velocity to the initial velocity between two objects after their collision. Therefore, with a coefficient of 0.45 and an initial speed of 100 m/s, the rebound speed is 0.45 * 100 m/s = 45 m/s.
