A 1000 N crate is being pushed across a level floor at a constantspeed by a force F of 500 N at an angle of 20° below thehorizontal
(a) What is the coefficient of kinetic friction between the crateand the floor?
(b) If the 500 N force is instead pulling the block at an angle of20° above the horizontal as shown in Figure P4.37b, what will bethe acceleration of the crate. Assume that the coefficient offriction is the same as found in (a).
