A person is pulled to the right on a sled (total mass of 60.1 kg) across the surface of a frozen pond with a force of 62.9 Newtons so that they move with a constant velocity. What is the force of friction acting on the sled? Choose your coordinate system so that upward, and to the right are each positive values.
