A ball is kicked at an angle θ = 45°. It is intended that the ball lands in the back of a moving truck which has a trunk of length L = 2.5m. If the initial horizontal distance from the back of the truck to the ball, at the instant of the kick, is Do = 5m, and the truck moves directly away from the ball at velocity V = 9m/s (as shown on the next page), what is the maximum and minimum velocity Vo so that the ball lands in the trunk? Assume that the initial height of 3 the ball is equal to the height of the ball at the instant it begins to enter the trunk.
