2. A block with a mass of m = 1.5 kg, being pushed across a horizontal glass surface, µg = 0.4. What is the value of the kinetic friction, Fr ? 3. A 75 kg block is pulled along the floor with a horizontal force of 100 N at a constant velocity. What is the coefficient of sliding friction between the block and the floor? 4. An 81-kg basketball player slides into the second base. The coefficient of kinetic friction between the player and the ground is 0.49. What is the magnitude of the frictional force?
