- 22.) If John lifts a 5kg object from dn 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 displadcement (both vertical). In doing work on it, John is also changing its GPE. Calculate the change in GPE of this scendrio.
