My maths and physics are rusty... I'm a bit ashamed, but I have this problem:
Let's have a 1000m linear accelerator (mass driver) propel a payload at constant acceleration, with a final velocity of 10km/s.
What I can't figure is how to calculate the necessary acceleration given these data.
I know that:
- $v(t) = a * t$
- $x(t) = \frac 12 * A * t^2$
- A is constant.
With all initial conditions at 0 (no speed, no acceleration, payload at the entry of the tube). All these equations take time as a parameter, whereas I don't know the time it takes, since I only have the final velocity.
How do I solve this?
