A 1,500-N crate is being pushed across a level floor at a constant speed by a force F of 370 N at an angle of 20.0° below the horizontal, as shown in figure a below.

(a) What is the coefficient of kinetic friction between the crate and the floor? (Enter your answer to at least three decimal places.)

(b) If the 370-N force is instead pulling the block at an angle of 20.0° above the horizontal, as shown in figure b, what will be the acceleration of the crate? Assume that the coefficient of friction is the same as that found in part (a).

The image consists of two diagrams labeled "a" and "b," each illustrating a wooden crate on a flat surface.

In diagram "a," a force vector \( \vec{F} \) is shown acting on the crate at a downward angle of 20.0 degrees from the horizontal. The vector is represented by a blue arrow pointing towards the crate, indicating a force being applied from above.

In diagram "b," the scenario is similar, with a force vector \( \vec{F} \) acting on the crate. However, in this case, the force is applied at an upward angle of 20.0 degrees from the horizontal. Here, the blue arrow points away from the crate in an upward direction.

Both diagrams depict how changing the angle of the applied force relative to the horizontal can affect the direction of the force on the crate.
