Question 43

A rollercoaster car with its motor turned off is coasting up a hill. As it climbs, its speed reduces. What are the energy transfers that take place during this ascent?

A

kinetic→gravitational+thermal (heat)\text{kinetic} \rightarrow \text{gravitational} + \text{thermal (heat)}kinetic→gravitational+thermal (heat)

B

gravitational→kinetic+thermal (heat)\text{gravitational} \rightarrow \text{kinetic} + \text{thermal (heat)}gravitational→kinetic+thermal (heat)

C

kinetic+gravitational→thermal (heat)\text{kinetic} + \text{gravitational} \rightarrow \text{thermal (heat)}kinetic+gravitational→thermal (heat)

D

thermal (heat)→kinetic+gravitational\text{thermal (heat)} \rightarrow \text{kinetic} + \text{gravitational}thermal (heat)→kinetic+gravitational
