The initial and final velocity must be zero and the maximum velocity can never exceed 1. The amount of thrust affects how much the rocket will speed up. Luckily at out university, most staff and students use Matlab for programming in their education (which runs on any operating system), therefore by converting the tutorial to Matlab would solve the first two evaluation points. The waveform represents the velocity trajectory of the Shuttle launch STS 103 in orbit. The thrusting phase corresponds to the first 3 s of the flight when the rocket motor burns, the coasting phase corresponds to the next 5 s of the flight when the rocket continues to fly. In this forthcoming "Getting started with Rocket Trajectory Calculations" pamphlet we'll learn how to apply Newton's equation F=ma in ever more precise ways to figure it all out. I seek to optimize payload by adjusting the thrust on-off times.

The rocket's supply of propellant will be exhausted after a burn of 150 seconds. However, their dispersion is quite large typically being around 5% of their range which for a typical 20 km range can be more than 1000 meters. Usually, a space mission will have at least one 'trajectory guy' that figures out what kinds of orbits are possible given the constraints as currently known (what rocket, when the launch window is, how much fuel, what kind of fuel, how long, desired final orbit, etc). Due to inherent layout concerns, simultaneous igni-tion of the SRMs is crucial to prevent mission failure precession and nutation angles. 2000, revised 17 Dec. skyward-matlab-rocket-simulator.

If you don't consider atmospheric drag and other dissipative effects, assuming that the Earth is non-rotating, and ignore general relativity (which is a lot of assumptions to make, and later I can try to edit this to comment on how they might be relaxed), a ballistic trajectory is just a segment of an orbit. Particularly, BITE can distinguish persistent forest, slow-onset disturbances and rapid-onset disturbances. Solving the equation: dV/dt = - W/m = -g. I seek to optimize payload by adjusting the thrust on-off times.
