Question

A box of mass m=7.0kg is placed on the floor of an elevator. At t=0, the elevator begins to accelerate upward at a

constant rate a=2.5m/s2, covering distance d=12.0m. Find the work done on the block by the normal force during that time interval and the instantaneous power created by the normal force at the end of that time interval.
