A force of 500 N is required to keep a piano (mass 200 kg) rolling down the hall at a comtant speed a. Find the frictional drag acting on the piano, b. If a total pull of 600N is now applied to the plano, find the rate at which it will accelerate c. We apply this accelerating force until the piano is traveling at a speed of 3.6 m/s. We then let go of the plano and let it coast to a stop. How far will it coast down the hallway before stopping? d. Find the coefficient of friction between the piano's rollers and the floor of the hallway I am sorry but please show work.
