Model rocket engines are rated by the impulse that they deliver when they fire. a particular engine is rated to deliver an impulse of 3.5 kg #m/s. the engine powers a 120 g rocket, including the mass of the engine. what is the final speed of the rocket once the engine has fired?

Final speed of the rocket,

Explanation:

It is given that,

Impulse delivered by an engine, J = 3.5 kg-m/s

Mass of the rocket, m = 120 g = 0.12 kg

To find,

The final speed of the rocket

Solution,

We know that the impulse is equal to the product of mass and velocity o it is equivalent to the change in momentum of an object.

So, the final speed of the rocket once the engine has fired is 29.16 m/s.

1= 26.17

2= 1.17

3=30.86

4=5.86
