A hot-air balloon is rising upward with a constant speed of 2.00 m/s. When the balloon is 3.37 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?

the height of the compass is

h = 3.37 + 2t - 4.9t^2
set h=0 to solve for t
