A 1000-N crate is being pushed across a level floor at a constant speed by a force of 280 N at an angle of 20.0° below the horizontal, as shown in the figure below.(a) What is the coefficient of kinetic friction between the crate and the floor?(b) If the 280 N force is instead pulling the block at an angle of 20.0° above the horizontal as shown in the figure, what will be the acceleration of the crate? Assume that the coefficient of friction is the same as that found in partm/s2
