Explanation 1) Concept: Here, we can use the second rocket equation to calculate the mass ratio in both cases. 2) Formula: V f - V i = V r e l × ln ⁡ M i M f 3) Given: The initial velocity of rocket, V i = 0 m / s 4) Calculations: We have, the second rocket equation as, V f - V i = V r e l × ln ⁡ M i M f Here, V f is the original speed of rocket relative to the inertial frame of reference. And V r e l is the exhaust speed
