A 40.0 kg steel ball is thrown upward from the leaning tower ofPisa with an initial speed of 4.90 m/s. The tower is 55m high.

a) What is the velocity (includes direction and magnitude) of theball just before it hits the ground?
b) Right after the releasing of the ball from hand, how long willit take for the ball to reach the highest point?
c) How long will it take for the ball to hit the ground?
