Answer

To determine the correct equation for calculating the kinetic energy (KE) of the car, we recall the formula for kinetic energy, which is given by:

$KE = \frac{1}{2}mv^2$

This formula indicates that the kinetic energy is proportional to the mass of the object (m) and the square of its velocity (v). Therefore, the correct option is:

C KE = \frac{1}{2}mv².
