A rock is thrown from the edge of the top of a 122 m tall building at some unknown angle above the horizontal. The rock strikes the ground a horizontal distance of 178 m from the base of the building 5.1 s after being thrown. Assume that the ground is level and that the side of the building is vertical. Determine the speed with which the rock was thrown.
