Question 39

A child on a sled pulls their sled from the bottom of a hill to the top and gains 12 000 J12\,000\text{ J}12000 J of gravitational potential energy.

They then sled down the hill. At the bottom of the hill, their kinetic energy is 3500 J.

How much energy is dissipated to the surroundings in overcoming friction and air resistance as the child sleds down the hill?

A

3500 J3500\text{ J}3500 J

B

8500 J8500\text{ J}8500 J

C

12 000 J12\,000\text{ J}12000 J

D

15 500 J15\,500\text{ J}15500 J
