Determine the length of the rough patch

Reference no: EM13492313

On an essentially frictionless horizontal ice-skating rink, a skater moving at 3.3 m/s encounters a rough patch that reduces her speed by 41% to a friction force that is 20% of her weight. Use the work-energy principle to find the length of the rough patch.
