Problem: A sled is pulled with a horizontal force of 18 N along a level trail, and the acceleration is found to be 0.36 m/s2. An extra mass m = 4.1 kg is placed on the sled.
Part A: 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?
I need help to determine the coefficient of kinetic friction between the sled and the trail.
