The time taken for an object to fall from rest through a certain distance on Mars is $T_M$. The time taken for the same object to fall from rest through the same distance on Earth is $T_E$. The acceleration of free fall on Mars is $3.71 m s^{–2}$.
Assume that air resistance is negligible on both Earth and Mars.
What is the ratio $\frac{{{T_M}}}{{{T_E}}}$?
