Some enterprising physics students working on a catapult decide to have a water balloon fight in the school hallway. The ceiling is of height 3.1 m, and the balloons are launched at a velocity of 9.8 m/s. The acceleration of gravity is 9.8 m/s2. At what angle must they be launched to just graze the ceiling? Answer in units of degrees.
