A 2 kg block is at rest on a rough surface. A horizontally applied force of 10 N is applied and after it has moved 6 m it has reached a speed of 5 m/s. What has been the work of the force of friction? Please Explain.
The work of the force of friction can be calculated using the equation W = Fd, where W is the work, F is the force, and d is the distance. In this case, the force of friction is equal to the applied force of 10 N, and the distance is 6 m. Therefore, the work of the force of friction is 10 N x 6 m = 60 J.
