83. A rocket of mass M moving at speed v ejects an infinitesimal
mass dm out its exhaust nozzle at speed vex. (a) Show that con-
servation of momentum implies that M dy = vex dm, where dy is
the change in the rocket's speed. (b) Integrate this equation from
some initial speed v; and mass M; to a final speed vf and mass Mf
Vf
to show that the rocket's final velocity is given by the expression
V₁ = V¡ + Vex ln(M¡/M₁).
