A boy can throw a ball up to a speed of `u = 30 m//s` . He throws the ball many a times, ensuring that maximum height attained by the ball in each throw is `h = 20 m`. Calculate the maximum horizontal distance at which a ball might have landed from the point of projection. Neglect the height of the boy. `[g = 10 m//s^(2)]`

Text Solution
