Question

Consider a spacecraft with electrical propulsion (I_sp= 2000 s and constant thrust T =0.1 N) in gravity-free space. The initial mass of the spacecraft is 300 kg. How long does it take to increase the velocity of the spacecraft with 2 km/s?

The answer is 66.02 days, but I would like to know the steps to that answer, Thanks!

Answer 1

m0 = initial mass = 300 kg
