WebTherefore, including both the change for the rocket and the change for the exhaust gas, the final momentum of the system is →p f = →p rocket + →p gas =(m−dmg)(v+dv)^i … WebThe motion of a rocket is essentially an effect of the conservation of momentum. That is, for a given isolated system, the total momentum will remain constant. Thus, if the main part of the rocket gains any speed in a given direction, it can only come from ejecting fuel with some velocity in the opposite direction. WebThe momentum of the ejected fuel gas is p = mgv. The ejection velocity v = 2.5 × 102m/s is constant, and therefore the force is F = dp dt = vdmg dt = −vdm dt. Now, dmg dt is the rate of change of the mass of the fuel; the problem states that this is 2.0 × 102kg/s . Substituting, we get F = vdmg dt = (2.5 × 102 m s)(2.0 × 102 kg s) = 5 × 104N. ramada wellington nz
