(a) Explanation Given Info : The exhaust velocity is 9.00 × 10 3 m / s , initial mass of rocket is 6.70 × 10 5 m / s and change in velocity of spacecraft during firing is 3.50 × 10 3 m / s . Write the formula to calculate the change in velocity during rocket propulsion. Δ v = v e ln ( M i M f ) Δ v is the change in velocity of rocket v e is the exhaust velocity M i is the initial mass of rocket M f is the final mass of rocket Rearrange the above equation in terms of Δ v v e . Δ v v e = ln ( M i M f ) Exponentiate the both sides of above equation. e Δ v v e = e [ ln ( M i M f ) ] The result of exponentiation is as follows. e Δ v v e = ( M i M f ) Rewrite the above equation in terms of M f (b) To determine The mass of fuel used by the rocket.
