a stone is projected at an angle of 60decree an and initial velocity of 20msper seconds. determine the time of the flight

I can't solve it
initial vertical velocity= 20sin60 m/s
hf=hi+20sin60*t - 4.9t^2
hf, hi are both zero, solve for time t.
This business of "I can't solve it is not much above whining". Showing some effort, or amplifying what you dont understand, or on stuck on, will lead to much better probability of success in life. Otherwise, one remains a baby.
