A sled of mass 'm' is being pulled horizontally by a constant horizontal force of magnitude F. The coefficient of kinetic friction is . During the time interval , the sled moves a distance 's', starting from rest.

1) Find the average power created by the force F.

2) Find the average velocity v_avg of the sled during that time interval.

3) Find the average power P_avg created by the force F in terms of the average speed v_avg of the sled.
Express your answer in terms of F and v_avg.
