How many seconds will the balloon be in the air

Reference no: EM13237891

A water balloon slingshot launches its projectiles essentially from ground level at a speed of 25.0m/s. (You can ignore air resistance.) Its angle to achieve max velocity is 45 degrees although I do not understand the trig it makes perfect sense. For how many seconds will the balloon be in the air?
