**Problem Statement:** A 1,460-N crate is being pushed across a level floor at a constant speed by a force \( \vec{F} \) of 290 N at an angle of 20.0° below the horizontal, as shown in figure a below. [Diagrams Description] The image includes two diagrams labeled "a" and "b": - **Diagram a**: Shows a crate with a force \( \vec{F} \) of 290 N being applied at a 20.0° angle below the horizontal level of the floor. - **Diagram b**: Similar to diagram a, but the force \( \vec{F} \) is applied at a 20.0° angle above the horizontal. **Questions:** (a) What is the coefficient of kinetic friction between the crate and the floor? (Enter your answer to at least three decimal places.) [Input Field for Answer] (b) If the 290-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). [Input Field for Answer] \( \text{m/s}^2 \)
