The coeffi cient of kinetic friction for the puck and the ice is 0.005 (a) What is the speed of the puck after travelling 58.5 m? (b) After being played on for a while, the ice becomes rougher and the coeffi cient of kinetic friction increases to 0.047. How far will the puck travel if its initial and fi nal speeds are the same as before?
