A 24 kg block is pushed 10.2 m along a level floor at constant speed with an applied force F directed 29 degrees below the horizontal (meaning it is directed somewhat downward). If the coefficient of kinetic friction between the block and the floor is μk = 0.19, what is the magnitude of the applied force F? |F→appl| = N By how much does the thermal energy of the block-floor system increase?
