A 1,040-N crate is being pushed across a level floor at a constant speed by a force F of 400 N at an angle of 20.0° below the horizontal. (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 400-N force is instead pulling the block at an angle of 20.0° above the horizontal, as shown in the 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).
