If two person is pulling a box in the same direction with 85 N and 65 N force. Find the net work done by the forces if net displacement of the box is 18m.
Forces are in the same direction, hence net force will be sum of these two forces.
Net force = 85 N + 65 N = 150 N
Displacement = 18 m
Net work done=Net force×displacement=(150 N)×18 m=2700J
