Question

A ball falls onto an inclined plane of inclination from a height h above the point of impact and undergoes a collision with coefficient of restitution e . Use = 45^ , e = 3 4 and h = 5 m . Find the maximum height reached by the ball after the collision.

Quantrex Academy · Accepted Answer

Correct answer: B. 18.5 m

The speed of the ball just before impact is v = 2gh . For an inclined plane, the component of velocity perpendicular to the plane is reversed and multiplied by e , while the parallel component remains unchanged. Using = 45^ and e = 3 4 , the rebound speed gives a maximum height of 18.5 m .
