The estimated cost, I think is 100 Billion to 1 Trillion Dollars.

Do you think this is absolutely foolish?

What if the NASA Space Ship had techinical problems while in Mars and so the Crew is stranded, do you think NASA will spend another trillion dollars to get the crew back?

Do you think that NASA will actually do this stupid mission?

PEgrav = mass * g * height
PEgrav = m * g * h
In the above equation, m represents the mass of the object, h represents the height of the object and g represents the acceleration of gravity (approximately 10 m/s/s on Earth).

I want to find out how many pounds of force there are behind a punch/kick...if i were using a weighted pendulum and based on how high it goes when you hit it, would this equation give me what i am looking for...if not what would?
