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 of the sled during that time interval.
3) Find the average power created by the force in terms of the average speed of the sled.
