I start off by looking at the equation which was F=Ma. Force is equal to mass times
acceleration, I dont know what acceleration is so I need to change the formula for acceleration
which would be A=forc
1. Our CEV can only hold a maximum of 4 people due to lack of supplies.
2. The weight of the CEV is another constraint because the CEV has to be able to get off the moon and
back to Earth. There has to be minimal thrusters to keep the weight down but they
