A father pulls his child on a sled by pulling on a rope over his
shoulder as shown. Using the coefficient of friction for steel on
ice from table 1, calculate the acceleration of the sled if its
mass plus the child is 22 kg, assuming the sled is already in
motion.

An Eskimo returning from a successful fishing trip pulls a sled loaded with salmon. The total mass of the sled and salmon is 50.0 kg, and the Eskimo exerts a force on the sled by pulling on the rope. The coefficient of kinetic friction between the sled and the ground is 0.200. (a) The Eskimo pulls the sled 6.00 m, exerting a force of 1.15 102 N at an angle of θ = 0°. Find the work done on the...
