**[SOLVED] Momentum. resulting velocity. Rocket**

## Homework Statement

On earth, an astronaut and equipment weigh 1,960.0 N. While weightless in space, the astronaut fires a 100 N rocket backpack for 2.0 s. What is the resulting velocity of the astronaut and equipment?

I have to be missing something. I tried using every formula given to me in class and I cannot get anywhere. Please help. Thanks.

## Homework Equations

p=mv

Ft= (mf)(vf)-(mi)(vi)

Ft=ma+v(difference of m/t)

m1v1=m2v2

## The Attempt at a Solution

I tried a few and can't get a relevant answer. I really do not know where to begin with the rocket.
