WebDuring the first part of the problem, the observed acceleration of the rocket was 27 m/s 2 and the rocket accelerated from zero to 86 m/s while traveling a distance of 140 m. Knowing these values at Point 2 allowed you to then learn about Point 3, with the understanding that the observed acceleration of the rocket between Points 2 and 3 was -9. ... WebMay 22, 2024 · Say my rocket could produce F newtons of thrust while consuming M 1 kilograms of fuel per second. It's mass at start is M 0, and it keeps burning until it reaches V velocity. How would I find out the necessary burn time for the rocket to reach V velocity?

WebThis tells us that a 2 centimeter thick shield would absorb 97.9% of the gamma rays. 2.1×10-2 = 0.021 = 2.1%. 100% - 2.1% = 97.9% . The main things that have to be shielded are the crew, the electronics, the cryogenic tankage, and the magnetic coils if this particular antimatter engine utilzes coils.
