As shown in the figure, a rod is placed on a horizontal surface with one end hinged and a ball moving with speed 5 m/s strikes it perpendicularly at the other end. If after the collision, rod starts rotating with angular speed 2 rad/s and the ball returns along the same path with 1.5 m/s, then coefficient of restitution for the collision is
Text Solution
Verified by ExpertsThe correct answer is:
C
Velocity of separation
L ω ω + 1.5 m/s = 2.5 m/s
Velocity of approach and separation are calculated by using velocities of the points of collision on the objects.
