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 g=10 m/s2g=10\ \text{m/s}^2g=10 m/s2.
Estimate the train’s acceleration. Then compare your result with the value of ggg.
