A solar propulsion engine uses solar power to ionize atoms of xenon and to accelerate them. As a result of the accelerationprocess, the ions are ejected from the spaceship with a speed of 3.0E4m/s
Mass of spaceship is 5.4E2
Engine ejects 7.7E18 ions every second and the fuel mass is 81 kg. Lasts for 4.8E7 secs.
My question is how do you find th initial acceleration? The IB book says that its 8.2E-5 but I've been getting 9.3E-5
please help me! My IB test is tommrowo!
thank you!
