Question

A rocket with the mass of 4 kg and has a momentum of 80 kg* m/s. What is the velocity of the rocket?

Answer 1

`20m\/s`

Step-by-step explanation

To find the velocity of the rocket, we have to apply the formula for momentum:

`p=mv`

where m = mass; v = velocity

Solve for the velocity:

`\begin{gathered} 80=4\cdot v \\ \Rightarrow v=(80)/(4) \\ v=20m\/s \end{gathered}`

That is the velocity of the rocket.
