Question

A body is allowed to fall on a steel plate from a height of 64 ft. It springs up to 36 ft. Its coefficient of restitution is.

Answer 1

Answer:

use this method and mark brainliest

Explanation:

we know that if ball is dropped from a height , h , velocity of particle just before hitting the ground will be v=(2gh)⇒v=(2g)

and if particle is projected with u , then it reaches a maximum height H then , u=(2gH)⇒u=(1.62g)

Now we know that, coefficient of restitution e=u1−u2v2−v1=−(2g)−00−(1.62g)=(0.81)=0.9

Answer 2

Answer:

A steel ball is allowed to fall freely from a height of 36 cm onto a smooth floor. Find the height to which it rises after rebounding from the floor. Coefficient of restitution between the steel ball and the floor = 0.60.
