A kid picks up a toy of mass 139g, from the floor. The kid lifts the toy 42.2cm above the floor.
(a) How much work does the kid do on the toy?
in joules
(b) The kid holds the toy stationary for 10 minutes, trying to figure out how to use it. How much work does the kid do during this time?
(c) The kid finds out she was not interested in the toy and puts it back on the floor. How much work does the kid do on the toy as she lowers it?
