A ball is projected from the point O with velocity 20 `m//s` at an angle of `60^(@)` with horizontal as shown in figure. At highest point of its trajectory it strikes a smooth plane of inclination `30^(@)` at point A. The collision is perfectly inelastic. The maximum height from the ground attained by the ball is `(g=10 m//s^(2))` img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/MPP_PHY_C07_E01_081_Q01.png" width="80%"
