3. You may have seen this question previously but now you will approach it using energy concepts. A pair of sleds weighs 25 kg and experience a frictional force of 25 N. If a dog team applies a 175 N force pulling it 12 m nd: a) the work done by friction. to) the work done by the dog team. c) the net work done (using the net force). How does then net work compare to the answers from the previous two parts of the question? d) What form of energy does the frictional force represent? What form of energy does the net force produce
