Question
A person holding a ball is on top of a building. The person jumped
at the rate of 1 ft/s while dropping the ball. After 12 seconds, the
ball hit the ground. Determine the following:
a. The initial velocity of the ball;
b. The time to reach the maximum height of the ball with
reference to the ball's starting point;
Ignore the dimensions of the ball and the height of the person. Use
g = -32 ft/s². Give exact answer i.e., do not round off answers.
