Jason jumped off of 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 long does it take Jason to hit the water?

• -16 seconds

• -6 seconds

• 0 seconds

• 5 seconds

If a toy rocket is launched vertically upward from ground level with an initial velocity of 128 feet per second, then its height, h, after t seconds is given by the equation h(t) = 16t² - 128t. How long does it take the rocket to hit the ground?

• 8 seconds

• 16 seconds

• -16 seconds

• -8 seconds
