Hi there(adsbygoogle = window.adsbygoogle || []).push({});

I'm in desperate need for your help!

I need to solve the rocket motion equation numerically in Maple or some other program. I'm having trouble writing the ODs

in the program.

I have derived the rocket motion equation in a single dimension:

[tex]

\frac {d\vec v_r(t)}{dt} = - \, \frac {\dot m_e(t)} {m_r(t)} \, \vec v_e(t)

[/tex]

I assume that the change of mass is constant and the exhaust velocity is constant. Let's say that the rocket has an initial mass of 1 kg, an empty mass of 0.1 kg and the exhaust velocity 5 m/s.

So, i want to solve the equation numerically in Maple or some other program (Maple is preferred) and find the expression for acceleration as a function of time, velocity as a function of time and the altitude as a function of time.
