##### Reference no: EM13544692

A 100 kg sled is slid across a smooth ice field by a group of four dogs tied to the sled pulling with a 350 N force along a rope at an angle of 20 degrees above the horizontal. (a) If the sled travels at a constant speed, find the drag force on the sled. (b) Find the work done by the dogs after pulling the sled for 1 km.
