You are moving into an apartment and take the elevator to the 6th floor. Suppose your weight is 690 N and that of your belongings is 1040 N. (a) Determine the work done by the elevator in lifting you and your belongings up to the 6th floor (15.2 m) at a constant velocity. (b) How much work does the elevator do on you alone (without belongings) on the downward trip, which is also made at a constant velocity?
