Questions
A ball is projected from the ground with speed 10 ms-1 at an angle 450 with horizontal. It collides with wall at a distance '4m' from the point of projection and returns to its original position. The coefficient of restitution between ball and wall is
detailed solution
Correct option is B
Since the wall is smooth, vertical component of velocity of the ball after the impact remains unchanged and horizontal component of velocity after the impact becomes (e x 10 cos450) m/s.Now , tOAP + tPBO = TTalk to our academic expert!
