You are slightly wrong in your calculation. The standard measurement for mass is the kilogram, so if you convert to grams you will have to divide the answer by 1000.
The easiest way for you (since you are starting out with kilograms) is just to use them, so the calculation becomes:
2,200,000,000 kg x 100 m/s2 = 220,000,000,000 N
Or 220 billion Newtons.
You also used the wrong measurement for acceleration. Remember, velocity is measured in m/s (metres per second); acceleration is measured in m/s2 (metres per second squared).
For the second part, Joules is a measurement of work done by a force over a specific distance. It is therefore calculated by multiplying the force by the distance traveled.
So you first need to know the distance your spaceship needs to travel (in metres) and then multiply that value by 220 billion Newtons to get the correct amount in Joules.
