A ball is projected from the point O with velocity 20 m/s at an angle of 60° with horizontal. 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
A juggler keeps on moving four balls in air throwing the balls after regular intervals. When one ball leaves his hand (speed = \(20\text{ ms}^{-1}\)), the position of other balls (height in metre) will be (take \(g = 10\text{ ms}^{-2}\))
