Solve the all parts of following problem given below:
Problem: Sam heaves a shot with weight 16-lb straight upward, giving it a constant upward acceleration from rest of 35.9m/s2 for a height 70.0cm. He releases it at height 2.17m above the ground. You may ignore air resistance.
Part A: What is the speed of the shot when he releases it?
Part B: How high above the ground does it go?
Part 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, a distance 1.85m above the ground?
Please show all work and steps to determine the speed of the shot when he releases it.
