You apply a constant 15 N force while pushing a box through a distance of 2.5 m across the floor.

a) How much work, in Joules, did you do?
b) If the box, starting from rest only gains 23 J of kinetic energy, how much of the work that you
did was converted into thermal energy through friction?

Answer:

Total work done  =force X displacement                      = 15 N X 2.5 m       [ given  F=15 N & d=2.5 m]                W   = 37.5 joules

this is just what i was able to find
