Question:

On an essentially frictionless, horizontal ice rink, a skater moving at 6.0 m/s encounters a rough patch that reduces her speed by 48 % due to a friction force that is 25 % of her weight.

Part A. Use the work-energy theorem to find the length of this rough patch. Express your answer using two significant figures.
