"The rate of fuel combustion is 0.7 \frac{kg}{\sec}.

Given data:

Rocket has the force = 210 N

Velocity = 300 m/s

Solution:

Rate of combustion of the fuel can be calculated by the formula of rate of combustion,

\left(\frac{d m}{d t}\right)=\frac{F}{u}

The rate of combustion is the ratio of force and velocity.

Rate of combustion of fuel is dm/dt which is equal to the force per unit velocity.

\Rightarrow \frac{dm}{dt}=\frac{210}{300}

\Rightarrow \frac{dm}{dt}=0.7 \frac{kg}{\sec }"
