Problem: A ball is thrown up from the top of the tower. For parts a-c, state whether the ball's acceleration is larger than g, equal to g, zero, or -g (assume up is positive and that g = 9.80 m/s2). (a) Just after leaving your hand and you are no longer touching it.(b) When the ball is at the top of the path.(c) Just before hitting the ground.
