A hot-air balloon is rising upward with a constant speed of 2.83 m/s. When the balloon is 8.64 m above the ground, the balloonist accidentally drops a compass over the side of the balloon. How much time elapses before the compass hits the ground?
Answered by drwls
Y = 8.64 + 2.83 t -4.9 t^2 = 0

Solve for t. Take the positive root of the quadratic
