Carol and Bruno drag a box of mass 58.0 kg along a frictionless floor. Carol pushes the box with a force of 11.4 N at an angle of 40.0 downward from the horizontal. Bruno pulls the

box from the other side with a force of 11.0 N at an angle of 40.0 above the horizontal. What is the net work done on the box if the displacement of the box is 14.5 m?

w=fdcos

11.4(14.5)cos40 get that value and add that to 11.0(14.5)cos40

answer: 2.49 x 10^2 J
