Tommy is working on a physics problem and asks his friend Sarah to check his work. He is to draw a free body diagram for a man walking to the left and comes up with the following: He reasons, “The man is walking to the left, so the force of friction is acting in the opposite direction. The normal force should be opposite and equal to that of the gravitational force.” Is Tommy correct with his diagram and reasoning? If so, explain. If not, what mistake did he make? Communication throughout the test will also be evaluated on 1) rounding using significant digits, 2) proper use of units, 3) organization and neatness, and 4) showing all work

A 1500-kg barge is being towed by means of two horizontal cables. One cable is pulling with a force of 90.0 N in a direction 25.0° west of north. Assume that the water exerts no appreciable frictional drag on the barge. Determine the following, showing all your steps clearly: a. In what direction should the second cable pull so that the barge will accelerate northward, if the force exerted by the cable is 130 N? Give your answer as an angle relative to north and state which direction (east of north or west of north). b. What is the acceleration that the barge moves north with? c. How far does it move in the first 15 seconds?
