Find coefficient of kinetic friction between sled and trail

Assignment Help Physics
Reference no: EM13288331

A sled is pulled with a horizontal force of 20 N along a level trail, and the acceleration is found to be 0.35 m/s2. An extra mass m = 4.2 kg is placed on the sled. If the same force is just barely able to keep the sled moving, what is the coefficient of kinetic friction between the sled and the trail?
