## To find the thrust on the rocket, we can use the formula for thrust, which is given by:Thrust=mass flow rate×velocity of the ejected gases1. Identify the mass flow rate: The mass flow rate of the fuel is given as 40kg/s.2. Identify the velocity of the ejected gases: The velocity of the gases ejected from the rocket is given as 5×104m/s.3. Substitute the values into the thrust formula: Thrust=40kg/s×5×104m/s4. Calculate the thrust: Thrust=40×5×104=200×104N5. Express in standard form: 200×104N=2×106NFinal Answer:The thrust on the rocket is 2×106N.
