Complete question is;

The cars in a soapbox derby have no engines; they simply coast downhill. Which of the following design criteria is best from a competitive point of view?

The car's wheels should;

A. have large moments of inertia

B. be massive

C. be hoop-like wheels rather than solid disks

D. have small moments of inertia

Answer:

D. The car's wheels should have small moments of inertia

Explanation:

They are simply cast downhill due to no engine and thus the solid wheels will have very small moments of inertia and will therefore accelerate at a faster rate.

Looking at the options, the correct one that corresponds to the description I just made is Option D.

The car's wheels should have small moments of inertia.

What is Inertia?

This is defined as the resistance of any physical object to a change in its velocity.

We told they were cast downhill due to no engine and the solid wheels having very small moments of inertia causing increase in acceleration depicts option D which was why it was chosen.
