A rocket that is 85% fuel by mass launches from the surface of Mars. Its exhaust velocity has a constant value of u = 2.9 × 103 m s−1. Determine the maximum launch duration if the rocket is to achieve a delta-v ▲v = 3.3 km s −1 -2 The acceleration due to gravity on Mars may be assumed to be a constant 3.71 m s−2.
