A ball is projected with velocity v_(0) = sqrt(gh) at an angle 'theta' to the horizontal towards a vertical smooth wall distant 'd' from the point of projection. After collision the ball returns to the point of projection. The coefficient of restitution is

A ball is projected with velocity v_(0) = sqrt(gh) at an angle 'theta'

1.	A ball is projected with velocity v_(0) = sqrt(gh) at an angle 'theta' to the horizontal towards a vertical smooth wall distant 'd' from the point of projection. After collision the ball returns to the point of projection. The coefficient of restitution is
Answer» `(d)/(h sin THETA - d)` `(d)/(2h sin theta-d)` `(d)/(h sin 2 theta-d)` `(d)/(sin 2theta + 2D)` Answer :C
