Answer:
The potential energy of the more massive one is twice that of the other.
Explanation:
Potential energy is given by
<em>PE</em> = <em>mgh</em>
where <em>m</em> = mass of body, <em>g</em> = acceleration of gravity and <em>h</em> = height or elevation.
For the less massive car, let the mass be . Then its <em>PE</em> is
For the massive car, let the mass be . Its <em>PE</em> is
But
Hence, the potential energy of the more massive one is twice that of the other.
