a stone is projected at an angle 60 degree and an initial velocity of 20m/s. determine the time of flight
Answered by oobleck
the stone's upward velocity is
v = 20 sin60° - 9.8t
how long does it take to stop rising? That's ha;f the total flight time.

Well I think the answer is calculated like this we are looking for our time (t) so therefore t=20(sin60°) and sin60 is =0.866 so 20 × 0.866 will give you 17.3secs
