The faster car has 9 times the kinetic energy of the slower car.
Explicar
## Step 1<br />The kinetic energy of an object is given by the formula:<br />### \( KE = \frac{1}{2}mv^2 \)<br />where \( m \) is the mass of the object and \( v \) is its velocity.<br /><br />## Step 2<br />If the velocity of the car is tripled, the kinetic energy will increase by a factor of \( 3^2 \), which is 9. This is because the velocity is squared in the formula for kinetic energy.<br /><br />## Step 3<br />Therefore, the faster car has 9 times the kinetic energy of the slower car.
