Find what is the work done by friction

Reference no: EM13691894

Compute the each part of given problem:

Problem: You are pushing a refrigerator across the floor of your kitchen. You exert a horizontal force of 318 N for 7.2 s, during which time the refrigerator moves a distance of 3.4 m at constant velocity.

Part I: What is the total work (by all forces) done on the refrigerator?

Part II: What is the work done by friction?

Thanks in advance that solve the above problem.
