Question 69

A child slides down a slide, starting from rest at the top (point P). After reaching the bottom, the child slides along a flat, high-friction safety mat and comes to a complete stop at point Q.

Which of the following describes the correct sequence of energy transfers that have taken place between P and Q?

A

kinetic→gravitational potential→internal (thermal)\text{kinetic} \rightarrow \text{gravitational potential} \rightarrow \text{internal (thermal)}kinetic→gravitational potential→internal (thermal)

B

gravitational potential→kinetic→internal (thermal)\text{gravitational potential} \rightarrow \text{kinetic} \rightarrow \text{internal (thermal)}gravitational potential→kinetic→internal (thermal)

C

gravitational potential→internal (thermal)→kinetic\text{gravitational potential} \rightarrow \text{internal (thermal)} \rightarrow \text{kinetic}gravitational potential→internal (thermal)→kinetic

D

kinetic→internal (thermal)→gravitational potential\text{kinetic} \rightarrow \text{internal (thermal)} \rightarrow \text{gravitational potential}kinetic→internal (thermal)→gravitational potential
