Often their labels are printed in a different color to help prevent you from using them in a typical rocket. Acceleration = resultant force divided by mass = 4.51 0.050 = 90 metres per second squared (90 m/s2). WebAverage thrust is the engines average push, or how fast the engine powers the rocket to go. You are better off writing the force balance equations if you understand them. Calculating the volume of a tube essentially involves the same formula as a cylinder ( volume=pr2h ), except that in this case, the diameter is used rather than the radius, and length is used rather than height. Note that in this calculator we consider only the flight to apogee. And for the model rocket to achieve a stable flight and not to complete its mission without leaving the launcher, the thrust-to-weight ratio must be at least 5:1[4] for the rocket to be moving at least 14 m/s (45 ft/s) by the time it leaves the launch rod or rail.
