The propulsive power of the rocket is (where v₁ = Jet velocity and v₂ = Aircraft velocity)

A. $$\frac{{{\text{v}}_1^2 - {\text{v}}_2^2}}{{2{\text{g}}}}$$

B. $$\frac{{{{\left( {{{\text{v}}_1} - {{\text{v}}_2}} \right)}^2}}}{{2{\text{g}}}}$$

C. $$\frac{{{\text{v}}_1^2 - {\text{v}}_2^2}}{{\text{g}}}$$

D. $$\frac{{{{\left( {{{\text{v}}_1} - {{\text{v}}_2}} \right)}^2}}}{{\text{g}}}$$

Answer: Option A

Solution(By Examveda Team)

The propulsive power of the rocket is $$\frac{{{\text{v}}_1^2 - {\text{v}}_2^2}}{{2{\text{g}}}}$$
Where ,
v₁ = Jet velocity
v₂ = Aircraft velocity
