Chapter 3.1, Problem 1dT

Recall the motion of the block in part B. For each force that you identified, state whether that force did positive work, negative work, or zero work on the block. Explain.

The sum of the works done by all forces exerted on an object is called the network, $W_{\text{net}}$ . Is the net work done on the block in part B positive, negative, or zero? Base your answer onyour free-body diagram and your knowledge of the block's motion.

Is the net work done on the block greater than, less than or equal to the work done by the net force on the block? Explain your reasoning.
