A 0.75 kg rock is projected from the edge of the top of a building with an initial velocity of 10.6 m/s at an angle 52° above the horizontal. Due to gravity, the rock strikes the ground at a horizontal distance of 17.9 m from the base of the building.
How tall is the building? Assume the ground level and that the side of the building is vertical. The acceleration of gravity is 9.8m/s^2
