Questions
A simple pendulum is hanging from a peg inserted in a vertical wall. Its bob is stretched in horizontal position from the wall and is left free to move. The bob hits on the wall the coefficient of restitution is . After how many collisions the amplitude of vibration will become less than 60°
detailed solution
Correct option is B
From the relation of restitution andTaking log of both sides we ge tlog1–log2 = n(log4–log5) 0–0.3010 = n(0.6020–0.6990)solving for n ≈3Similar Questions
