I am using the derivative of momentum (dp/dt) with Newton’s 3rd Law with the gravitational force of Earth.
F - [Force of gravity on rocket] = dp/dt
F - (G * m_e * m_r / r2 ) = v * dm/dt + ma
F = Force created by fuel (at time t)
G = Gravitational Constant
m_e = Mass of Earth
m_r = Mass of...
Hello, I am trying to understand the maths/physics/chemistry behind this situation. Here is the scenario. I have 8 grams of pressurized N2O in a cylinder at 60 bar/ 900 psi. If the temperature stays constant (let's say 50-70°C, or at a temperature where the N2O can stay as pressurized as...
Is there any equation in order to know how high my rocket will go, before launching it? I suppose that if there is any, it will not take into account air drag and others, and there is no need for that. I just one to know an approximate, I am making a summer project with some friends and we had...
Lets assume you could fire a 100kg projectile using a coilgun at 1 degree above the horizon and have it arrive safely at 400km altitude travelling at 7.8km/s (or slightly more if that helps).
How much delta-v would it need to correct its trajectory into a stable orbit?
If it matters lets...
Homework Statement
A truck hauling a big tank of oil starts at position x=D (Chicago) and heads due west (–x direction) toward its destination at x = 0 (Des Moines). At Chicago, the total mass of the loaded truck is M and the mass of oil it is carrying is λM. (Thus M(1–λ) is the "tare" mass =...
