A worker slides a piece of equipment into place, first moving it a distance of 3.5 m to the left and then forwards a distance of 4.6 m. If kinetic friction is 59.0 N, determine the additional work done (J) in moving it left then forwards as opposed to moving it directly into place.

Hint: recall that total work done by friction & air-resistance depends on the path distance, not displacement

Consider: why is the force applied in overcoming static friction not considered?
