A rescue plane is flying horizontally at a height of 132 m above the ground. The pilot spots a survivor and releases an emergency kit with a parachute. The kit descends at a constant vertical acceleration of -6.89 m/s^2 and the initial plane horizontal speed is 68.9 m/s. Assuming air resistance and wind are negligible, how long will the emergency kit be falling through the air?

1. distance = 1/2 * acceleration * time^2

-132 = 1/2 * -6.89 * t^2
