### Single Stage Rocket

Using the expression:

v_{f} - v_{i} = v_{e}ln(M_{i}/M_{f}),

make an estimate of the greatest possible v_{f} that can be attained in a single stage rocket.

A ratio of (M_{i}/M_{f}) = 10 is reasonable, and exhaust speeds of the order of 2000-3000 *m/s* are attainable.

The escape velocity of the earth is given by:
