I tried this....

#### Explanation:

The only thing I can think of is coming from the basic expression for Kinetic Energy:
$K = \frac{1}{2} m {v}^{2}$
that tells us that there is a direct proportionality between kinetic energy $K$ and mass $m$, so that when you increase the mass of a moving object the kinetic energy will also increase, i.e.:
let us consider a car travelling at, say, $60 \frac{k m}{h}$ and having mass of $1000 k g$; when you have the same car travelling at the same velocity but now with double the mass (you are carrying your mates) the kinetic energy will double as well.
