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.
