An object of mass m is dropped from the roof of a building of height h . While the object is falling, a wind blowing parallel to the face of the building exerts a constant horizontal force F on the object. (a) How long does it take the object to strike the ground? Express the time t in terms of g and h . (b) Find an expression in terms of m and F for the acceleration a x of the object in the horizontal direction (taken as the positive x -direction). (c) How far is the object displaced horizontally before hitting the ground? Answer in terms of m , g , F , and h . (d) Find the magnitude of the object’s acceleration while it is falling, using the variables F , m , and g .
