Jason jumped off a cliff into the ocean in Acapulco while vacationing with some friends. His height as a function of time could be modeled by the function h(t) = -16t2 + 16t + 480 , where t is the time in seconds and h is the height in feet.

How far off the ground was Jason when he jumped?

480 feet

1. A trebuchet launches a projectile on a parabolic arc from a height of 47 ft at a velocity of 40 ft/s. Using the function h(t) = -16t2 + 40t + 47 , determine when the projectile will first reach a height of 60 ft and how many seconds later it will again be at 60 feet.

It will be at 60 feet at .384 seconds and 2.116 seconds or 1.732 seconds apart.
