The crates' direction of acceleration is opposite the direction of motion. The net force in both cases points in the upward direction.
Two crates, A and B are in an elevator as shown. The mass of crate A is greater than the mass of crate B. As the elevator approaches its destination, its speed decreases (it continues to move downward).
In the spaces provided below draw arrows to indicate the direction of the net force on each crate. If the net force on either crate is zero, state so and explain.
