Answer:

W = 29.5 J

Explanation:

It is given that,

Force acting on a freight cart is 59 pounds

We need to find the work done in moving the cart 80 feet if the cart’s handle makes an angle of 30° with the ground. The product of force and displacement is called work done. It can be written by :


W=F_x* d


F_x is the horizontal component of force


W=59* \cos30* 80\\W= -29.5\ J

So, the magnitude of work done by the cart is 29.5 J.
