Question 138

A cyclist rides from the bottom of a hill to the top, gaining 15 000 J15\,000\text{ J}15000 J of gravitational potential energy. She then coasts down the hill without pedaling. At the bottom of the hill, her kinetic energy is 4 500 J4\,500\text{ J}4500 J. How much energy was converted into thermal energy and sound energy as the cyclist coasted down the hill?

A

4 500 J4\,500\text{ J}4500 J

B

10 500 J10\,500\text{ J}10500 J

C

15 000 J15\,000\text{ J}15000 J

D

19 500 J19\,500\text{ J}19500 J
