The function h(t) = -16t2 + vt + c models the height in feet of a golf ball after t seconds when it is hit

with initial vertical velocity v from initial height c feet. A golfer stands on a tee box that is 21 feet above

the fairway. He hits the golf ball from the tee at an initial vertical velocity of 64 feet per second.
