Question

A rock is projected from ground level. Later, 4.0 s after being projected, the rock is observed to strike the top of a 9.75 m tall fence that is a horizontal distance of 240 ft (yes these are different units) from the point of projection. Determine the speed with which the rock was projected. (1 m = 3.281 ft)
