A stone is thrown from the top of the tower at an angle of 30 with the horizontal with a velocity of 16m/s after 4 s of flight it strikes the ground calculate the height of the tower from the ground and the horizontal range of stone (g=9.8m/s2)

Answer:
Explanation:
height = usinthet*time-gt²/2
= 8*4-9.8*4*4/2
= 32-78.4
= 46.4 m? (here height comes off as negative because we're taking it in the direction of gravity)
