Question

Below. Sam heaves a 16 lb shot straight up, giving

it a constant upward acceleration from rest of 35.0 m/s2 for 64.0 cm.

He releases it 2.20 m above the ground. Ignore air resistance. 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?
