The fastest roller skater skated over 402 m, reaching a final velocity of 20.5 m/s. Suppose this roller skater has a mass of 61.4 kg. What is the total change in the internal energy of the skates, wheels, and ground as the skater skates past the finish line?The fastest roller skater skated over 402 m, reaching a final velocity of 20.5 m/s.
