(I have the answers for #1 and #2, I need help for the rest of those.)

Let's say we want a drive that can produce 100 mNewtons of thrust for 4 years. We settle on a 2,000-volt difference in voltage for the drive grids.

1. How fast will each Xenon atom be leaving the thruster? _____________m/sec ( COE)

2. Working with 1 second of time and using the impulse equation from last semester what force will each atom put on the spacecraft ? ________________ newtons. F*dt=m*dv

3. So how many Xenon atoms per second will be required to generate a total thrust on 100 mN? _______________________________atoms

4. Knowing 1 atom of Xenon has a mass of 131.29 AMU's, what is the rate of mass used per second ? _____________Kg

5. If your drive is going to keep going for 4 years what is the propellent mass needed

__________________Kg on the spacecraft .

6. If you space craft mass in 1000 Kg and start at v=0 m/s, How fast would you be going at the end of the 4 years? _______________m/s
