HW15:  Problem from our lab experiment:

Katie though the baseball straight up outside and it took
3.1 seconds for the ball to reach the ground. The ball left her
hand at a height of 4.75 feet. We know that the equation governing
the height of the ball at any given time is this:

s = -16*t^2 + v0 * t + h0

(where t is the number of seconds after the ball left her hand,
h0 is the height of the ball when it left her hand,
v0 is the initial velocity at which she threw the ball).

Our questions for homework are these:

1) How fast did Katie throw the ball (what is v0)?

2) How high did the ball go?
