Question

A stone is thrown from the top of a tower at an angle of 30° up with the horizontal with a velocity of 16m/s.after 4sec it strikes the ground.calculate the horizontal range of the stone

Answer 1

V (horizontal) = 16Sin(30) = 8m/s

using S = ut-1/2gt^2 = 8*4 = 32m (g in horizontal axis is zero)
