A 2.20 kg block is initially at rest on a horizontal surface. A horizontal force of magnitude 4.83 N and a vertical force are then applied to the block (Fig. 6-17). The coefficients of friction for the block and surface are µs = 0.4 and µk = 0.25. Determine the magnitude of the frictional force acting on the block if the magnitude of is (a) 8.00 N and (b) 12.0 N. (The upward pull is insufficient to move the block vertically.)
A package is projected 10 m upward on a 15 ° inclined plane so that it reaches the top of the plane with zero velocity. Knowing that the coefficient of kinetic friction between the package and the incline is 0.15, determine the speed of the package when it returns to its original position.
