At t = 0, truck, starting from rest, moves in the positive x-direction at uniform acceleration of 5 ms −-− 2. At t = 20 s, a ball is released from the top of the truck. The ball strikes the ground in 1 s after the release. The velocity of the ball, when it strikes the ground, will be : (Given g = 10 ms −-− 2)
