Rotational Motion Question 114

Question: A ball is projected in a direction inclined to the vertical and bounces on a smooth horizontal plane. The range of one rebound isR . If the coefficient of restitution is e , then range of the next rebound is

Options:

A) R=eR

B) R=e2R

C) R=Re

D) R=R

Show Answer

Answer:

Correct Answer: A

Solution:

[a]

R=2ucosθ.usinθg

After impact horizontal component remains the same = ucosθ

The vertical component becomes V=e(sinθ)

New range R=2ucosθ.eusinθgR=eR
