Question 155

A cyclist climbs to the top of a hill, gaining 24 000 J24\,000\text{ J}24000 J of gravitational potential energy. She then freewheels down the hill. At the bottom of the hill, her kinetic energy is 9 000 J9\,000\text{ J}9000 J. How much energy is dissipated in overcoming friction and air resistance during the descent?

A

9 000 J9\,000\text{ J}9000 J

B

15 000 J15\,000\text{ J}15000 J

C

24 000 J24\,000\text{ J}24000 J

D

33 000 J33\,000\text{ J}33000 J
