A 1 000-N crate is being pushed across a level floor at a constant speed by a force of 300 N at an angle of 20.0° below the horizontal, as shown in (a), a. What is the coefficient of kinetic friction between the crate and the floor? b. If the 300-N force is instead pulling the block at an angle of 20.0° above the horizontal, as shown in (b), what will be the acceleration of the crate? Assume that the coefficient of friction is the same as that found in a.
