You are pushing a refrigerator across the floor of your kitchen. You exert a horizontal force of 294 N for 7.6 s, during which time the refrigerator moves a distance of 3.2 m at constant velocity.
(a) What is the total work (by all forces) done on the refrigerator?
(b) What is the work done by friction?

work=294*3.2
friction=above work done, since there is no change in KE, or PE
