Impulse & Momentum Conservation

The force on a rocket moving with a velocity $300\text{ m/s}$ is $210\text{ N}$ . The rate of consumption of fuel of rocket is

Show answer and solution

Answer: (a)

Thrust $F = u\frac{dm}{dt}$ .
$\frac{dm}{dt} = \frac{210}{300} = 0.7$ kg/s
So the answer is (a) $0.7$ kg/s.
