Energy Theorem and Kinetic Energy: Coefficient of Friction

Question: A 16-kg sled is being pulled along the horizontal snow-covered ground by a force of 24 N. Starting from rest, the sled attains a speed of 2.0 m/s in 8.0 m. Find the coefficient of kinetic friction between the runners of the sled and the snow.

Solution Preview

The way to solve this problem is conservation of energy.

Calculate the work done by the runners and then calculate the final kinetic energy.Write down the expression for the work lost to friction. This term includes the friction coefficient.

Conservation of energy:

Work done by the runners - ...
