Vedclass · Answer

(B) Given,mass of the rocket $m = 2 	imes 10^4 \ kg$.Initial acceleration $a = 5 \ m \ s^{-2}$.Acceleration due to gravity $g = 10 \ m \ s^{-2}$.The initial thrust $F$ must overcome the gravitational force $(mg)$ and provide the required acceleration $(ma)$.According to Newton's second law,$F - mg = ma$.Therefore,$F = m(a + g)$.Substituting the values: $F = (2 	imes 10^4 \ kg) 	imes (5 \ m \ s^{-2} + 10 \ m \ s^{-2})$.$F = 2 	imes 10^4 	imes 15 \ N$.$F = 30 	imes 10^4 \ N = 3 	imes 10^5 \ N$.

$A$ rocket with a lift-off mass $2 \times 10^4 \ kg$ is blasted upwards with an initial acceleration of $5 \ m \ s^{-2}$. The initial thrust of the blast is (Take $g = 10 \ m \ s^{-2}$)
