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? Elevator Explain. A ii. In the spaces provided below, draw and label separate free-body B diagrams for the crates. Constant speed Free-body diagrams Crate A 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 Direction of net force crate. If the net force on either crate is zero, Crate A Crate B state so explicitly. Explain. Is the magnitude of the net force on crate A greater than, less than, or equal to that on crate B? Explain.b. As the elevator approaches its destination, its speed decreases. (It continues to move downward.) i. How does the acceleration of crate A compare to that of crate B? Explain. ii. In the space provided below, draw and label separate free-body diagrams for the crates in this case. Free-body diagrams Crate A 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 Direction of net force crate. If the net force on either crate is zero, Crate A Crate B state so explicitly. Explain. Is the magnitude of the net force acting on crate A greater than, less than, or equal to that on crate B?
