Draw a sketch and also a good FBD to identify the relevant forces doing work. A pair of sleds weighs 25 kg (total) and experience a frictional force of 25 N (in total). If a dog team applies a 175 N force pulling it 12 m find: a) the work done on the sleds by friction b) the work done on the sleds by the dog team. C) the net work done (using the net force). How does the net work compare to the answers from the previous two parts of the question?
