Question 48

A cyclist rides to the top of a hill and gains 18,000 J18,000\text{ J}18,000 J of gravitational potential energy.

The cyclist then coasts down the hill without pedaling. At the bottom of the hill, their kinetic energy is 5,000 J5,000\text{ J}5,000 J.

How much energy is dissipated in overcoming friction and air resistance as the cyclist coasts down the hill?

A

5,000 J5,000\text{ J}5,000 J

B

13,000 J13,000\text{ J}13,000 J

C

18,000 J18,000\text{ J}18,000 J

D

23,000 J23,000\text{ J}23,000 J
