The kinetic energy (KE) of an object can be calculated using the formula:
\[ KE = \frac{1}{2}mv^2 \]
where:
- \( m \) is the mass of the object (in kg),
- \( v \) is the velocity of the object (in m/s).
In this case:
- \( m = 1500 \) kg,
- \( v = 20 \) m/s.
Now, let's calculate the kinetic energy:
\[ KE = \frac{1}{2} \times 1500 , \text{kg} \times (20 , \text{m/s})^2 \] \[ KE = \frac{1}{2} \times 1500 \times 400 \] \[ KE = \frac{1}{2} \times 600000 \] \[ KE = 300000 , \text{J} \]
Thus, the kinetic energy of the car is 300,000 J.
