i have no clue where to begin to solve this problem. Can anyone help me out and get me started please and thanks. A hockey puck, sliding on an outdoor rink, has a velocity of 19 m/s forward when it suddenly hits a rough patch of ice that is 5.1 m across. Assume that the coefficient of kinetic friction between the puck and the rough ice is 0.47. Determine the time it takes the puck to clear the rough ice.
