A block with a mass of 8 kg is at rest on a horizontal surface. The coefficiant of static friction between the block and the surface is 0.25, and the coefficient of kinetic energy is 0.20. A force of 15 N acts on the block toward the left. What is the magnitude of the frictional force on the block.
