Question

Bonny Blair of the United States set a world record in speed skating when she skated 5.00 x 10^2 m with an average speed of 12.92 m/s. Suppose Blair crossed the finish line at this speed and then skated to a stop. If the work done by friction over a certain distance was −2830 J, what would Blair’s kinetic energy be, assuming her mass to be 55.0 kg?
