## Newton's Second and Third Laws ### Problem 2 Two crates, A and B, are in an elevator as shown. The mass of crate A is greater than the mass of crate B. ### a. The elevator moves downward at constant speed. **i.** How does the acceleration of crate A compare to that of crate B? Explain. **ii.** In the spaces provided below, draw and label separate free-body diagrams for the crates. - **Free-body diagram for crate A:** - **Free-body diagram for crate B:** **iii.** Rank the forces on the crates according to magnitude, from largest to smallest. Explain your reasoning, including how you used Newton's second and third laws. **iv.** In the spaces provided at right, draw arrows to indicate the direction of the net force on each crate. If the net force on either crate is zero, state so explicitly. Explain. - **Direction of net force:** - Crate A - Crate B **Is the magnitude of the net force on crate A greater than, less than, or equal to that on crate B? Explain.** ### Diagram Explanation #### Free-body Diagram The diagram showing two crates, labeled A (top) and B (bottom), within an elevator. The elevator is indicated to be moving downward with constant speed, as denoted by an arrow labeled "Constant speed." A cable supports the elevator, illustrating the setup for this problem.
