Find the maximum height of ball using given equation.
Suppose Charlie O' Brian hits a baseball straight upward at 150 ft/sec from a height of 5 ft.
a) Use the formula to determine how long it takes the ball to return to the earth.
b) Use the graph on the next page to estimate the maximum height reached by the ball. If an object is given a initial velocity of v0 feet per second from a height of s0 feet, then its height S after t seconds is given by the formula s= -16t2+ v0t+s0
