Gravity is still the only force acting vertically so we can find the total time in the air from kinematics: vy = 0 at the top = v0sin – gt giving t (to the top) = v0sin/g and the total time is twice the time to the top, or 2v0sin/g. In this time, the ball is also accelerating horizontally (think ...
