Step 1
Which of these is the correct equation for calculating the kinetic energy of the car?
Answer
The kinetic energy (KE) of an object is given by the formula:
where:
- m is the mass of the object,
- v is the velocity of the object.
Among the given options, the correct one is:
C KE = \frac{1}{2}mv²
