2 Motion and forces

A train pulls away from a station. Its velocity increases from zero to about 12 m/s in about 24 s.

Near the Earth’s surface, take the acceleration of an object in free fall to be $m/s2g=10\ \text{m/s}^2$ .

Estimate the train’s acceleration. Then compare your result with the value of $g$ .
