Asked by Christian

A rocket of mass 1000 kg containing a propellant gas of 3000kg is to be launched vertically. If the fuel is consumed at a rate of 60kgs-1, calculate the least velocity of the exhaust gasses if the rocket and content will just lift off the launching pad immediately after firing

F = d/dt(mv) = m g = 4000 *9.81

v * 60kg/s = 4000 * 9.81
