Sam heaves a 16-lb shot straight upward, giving it a constant upward acceleration from rest of 45.0 m/s' for 64.0 cm. He releases it 2.20 m above the ground. You may ignore air resistance.

(a) What is the speed of the shot when Sam releases it?

(b) How high above the ground does it go?

(c) How much time does he have to get out of its way before it returns to the height of the top of his head, 1.83 m above the ground?
