Question by : An ion propulsion rocket was used to accelerate a space probe. Ions of Xenon gas were ejected at high speed?
Calculate the force exerted by an ion propulsion rocket on a space probe, and hence determine its acceleration is 7.35*10^-5.
Here is some additional information:
Mass of space probe = 490kg
Speed of ejection of ions = 3.0*10^4 m/s
Rate of ejection of ions = 1.20*10^-6 kg/s (0.104 kg per day)
Answer by Steve
F = ṁ*v = 1.2E-6*3E4 = .036 N
a = F/M = .036/490 = 7.35E-5 m/s²
