A load of bricks is being lifted by a crane at the steady velocity of Vo (= 5 m/s) when one brick falls of H (= 5m) above the ground. Describe the motion of the free brick by sketching x(t).
a. What is the greatest height above the ground that the brick reaches?
b. How long does it take to reach the ground?
c. What is its speed just before it hits the ground?
