a cricketer throw the ball to have maximum horizontal range of 120m.if he throws the ball vertically with same velocity what is the maximum height it can reach?
Maximum horizontal range is achieved when thrown at an angle of 45 degrees, and equals Vo^2/g. (Vo is the initial velocity). Maximum height when thrown verticslly is
Vo^2/(2g), half as much as maximum range.
