Question

a rocket of mass 1000 kg exhaust gases at a rate of 4 kg / sec with a velocity 3000 m/s the thrust developed on the rocket is​

Answer 1

Answer:

12000N

Explanation:

F=V× dm/dt=12000

Answer 2

Answer:

The thrust developed on the rocket is 12000 N.

Explanation:

Given that,

Mass of rocket = 1000 kg

Velocity = 3000 m/s

Rate of exhaust gases = 4 kg/s

We need to calculate the thrust developed on the rocket

Using formula of thrust

$F=u\times\dfrac{dm}{dt}$

Where, u = velocity

$\dfrac{dm}{dt}$=rate of exhaust gases

Put the value into the formula

$F=3000\times4$

$F=12000\ N$

Hence, The thrust developed on the rocket is 12000 N.
