Unformatted text preview: A m the areatomass ratio and v V r the relative velocity of the air. That is, v V r = v V airv V rocket . This formula is a priori de²ned relative to an inertial frame. However, show that it is the same in a rotating frame (that is with velocitied computed in a rotating frame). 2. Similarly we derive the equation for thrust:dm dt v V e relative to an inertial frame of reference. Here v V e is the velocity of the exhaust gas relative to the rocket velocity. Does this velocity depends on the frame in which it is measured? 3. Write down the equations of the rocket in an Earth centered inertial frame and an Earth centered ²xed frame including (nonconstant) gravitation, thrust and drag . Explicit the initial conditions. 1...
