A person is pushing a baby stroller forward (toward the left on your free body diagram) using one hand. Given the information below, draw a free body diagram of the hand (7 marks), and then draw a free body diagram of the forearm (5 marks). Follow the steps and sign convention outlined in Module A. Assume the hand force acts at the metacarpophalangeal (MCP) joint. Determine the horizontal and vertical joint reaction forces and the net joint moment at the wrist (10 marks).
