Re: [amsat-bb] 400N P3D Rocket

[David Rush <ky0dr@xxxxxxxx>]

At the risk of embarrasing myself, here's my calculated:

400 N = 400 kg(m/sec*sec)

(400 kg*m/(sec*sec)) / (115 kg) = accel rate of (400/115) m/(sec*sec)

So, at that rate, how long does it take to reach 100 km/hour = (1000/36) m/sec?

I threw the numbers around until the dimensions come out right:

( (1000/36) m/sec) / ( (400/115)*(m/sec*sec) ) = 7.99 seconds.

Hold on tight.  That's 0-65 in under 8 secs.

David, ky0dr
