# Hyperloop: Dropping coins

The Hyperloop is a hypothetical new fast transport system between cities, which works by launching pods that carry people through a very low air pressure tunnel. While riding in the Hyperloop, some coins fall out of your pocket, taking 1/3 of a second to hit the ground. How much more quickly would the coins have hit the ground if you were sitting still in seconds?

• The radius of the earth is $$6370~\mbox{km}$$.
• The Hyperloop travels at $$300~\mbox{m/s}$$.
• The acceleration of gravity is $$-9.8~\mbox{m/s}^2$$.
