33) This problem asks us to find the net work done on the object during the 5 meter displacement. This is different from problem 32, which simply asked about the work done by F = 10 N. There are two ways we could try to find the net work done.
The orange equation is the best way to solve this equation because all we need to know is the starting speed, the final speed, and the mass. Although we aren't given any of these, the problem tells us that the velocity is constant, we know that the final speed will be equal to the initial speed.
Answer: A
