Solve the below problem:
Q: (a) A 60-kg woman rides a 7-kg bicycle up a 3 percent slope at a constant speed of 2 m/s. How much power must be developed by the woman?
(b) A 90-kg man on a 9-kg bicycle starts down the same slope and maintains a constant speed of 6 m/s by braking. How much power is dissipated by the brakes? Ignore air resistance and rollingresistance.
