You are trying to find out how high you have
to pitch a water balloon in order for it to burst
when it hits the ground. You discover that
the balloon bursts when you have pitched it
to a height of 18 m.
With what velocity did the balloon hit
the ground? The acceleration of gravity is
9.8 m/s². The positive direction is up, so the
velocity when it hits is negative.
Answer in units of m/s.
