A solid iron ball is shot out of a cannon such that it’s vertical speed is 26 m/s which horizontal speed is 30 m/s. How long will the ball be in the air?

Answer 1

The time of flight will not depend on the horizontal speed.

The equation of vertical motion (assuming that the ball was shot from height = 0) is

s(t) = 26t - 16t² and the time of flight is found when s(t) = 0 for t≠0.
