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))`

A ball is projected from the point O with velocity 20m//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 75/k meter. Find the value of k ? (g=10m//s^(2))

A ball is projected from point A with velocity 20 m/s prependicular to the inclined plane as shown in figure. What is the range of the ball on the inclined plane ?

A ball is projected from a point in a horizontal plane with a velocity of 20 m/s at 30^(@) with the horizontal. Coefficient of restitution is 0.8, then
