Some enterprising physics students working
on a catapult decide to have a water balloon
fight in the school hallway. The ceiling is of
height 3.7 m, and the balloons are launched
at a velocity of 13 m/s.
The acceleration of gravity is 9.8 m/s².
At what angle must they be launched to
just graze the ceiling?
