The inclined plane is smooth and horizontal plane is rough. The ball placed at A collides elastically with similar ball placed at C. After moving a distance R, the ball at C stops:
- the deceleration of ball A on horizontal plane is µg, if µ is the coefficient of friction.
- the deceleration of ball A on horizontal plane is 2µg.
- the value of coefficient of friction is 0.25
- the value of coefficient of friction is 0.50
Answer
(A) the deceleration of ball A on horizontal plane is µ g, if µ is the coefficient of friction., (D) the value of coefficient of friction is 0.50
