What is the work done by friction

Reference no: EM13672860

You are pushing a refrigerator across the floor of your kitchen. You exert a horizontal force of 306 N for7.2 s, through which time the refrigerator moves a distance of 3.1 m at a constant velocity.

a) What is the work done by friction?

b) What is the total work (by all forces) done on the refrigerator?
