- 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).A force of 39.0 NN is required to start a 6.0-kgkg box moving across a horizontal concrete floor.

The rope pulls horizontally on the lower crate, and the coefficient of static friction between the lower crate and the roof is 0.707. What is the weight of the heaviest pallet of bricks that can be supported this way? (Hint: Start by drawing appropriate free-body diagrams.)

Be sure to explain your answer fully and using the principles from Newton law and friction.An athlete is about to step out of bounds during a basketball game so he plants his foot right at the edge of the line. However, since the traction is not enough, his shoe instead slides across the floor and beyond the out of bounds line (see Figure 5). If the magnitude of the net downward force that the human-shoe system exerts on the floor is 350 N350 N, and the shoe slides in the influence of a frictional force of 270 N270 N, what is the coefficient of kinetic friction between the shoe and the floor?
