22.) If John lifts a 5kg object from an initial height of 4m to a height of 9m and places it at the top of a shelf, John is doing work on it, since he is applying a force that is in the direction of its displacement (both vertical). In doing work on it, John is also changing its GPE. Calculate the change in GPE of this scendrio. (use g = 9.81ms-2).
