Explain

## Step 1:<br />To find the kinetic energy of the car, we use the formula for kinetic energy:<br />### \(\mathbf{K = 0.5 \cdot m \cdot v^2}\)<br />where \(K\) is the kinetic energy, \(m\) is the mass of the car, and \(v\) is the velocity of the car.<br /><br />## Step 2:<br />Substitute the given values into the formula:<br />- \(m = 1400 \, \mathrm{kg}\)<br />- \(v = 30 \, \mathrm{m/s}\)<br /><br />### \(\mathbf{K = 0.5 \cdot 1400 \cdot 30^2}\)<br /><br />## Step 3:<br />Calculate the value of \(K\):<br />### \(\mathbf{K = 0.5 \cdot 1400 \cdot 900}\)<br />### \(\mathbf{K = 700 \cdot 900}\)<br />### \(\mathbf{K = 630,000}\) Joules
