A dynamics cart with a force sensor is placed on a level track. Attached to the force sensor is a string of negligible mass that passes over a pulley. A hanging mass is then attached to the free end of the string and the cart is released from rest. Draw a picture of this situation and label all of the forces present. Ignore friction on the axels of the pulley and cart. Also draw free body diagrams for both the cart and the hanging mass below.
