Pretty clumsy balloonist. Can't hold onto his compass for much over a second!
A hot-air balloon is rising upward with a constant speed of 2.10m/s. When the balloon is 3.18m 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?
