## Homework Statement

A 30 kg girl standing on slippery ice catches a 0.5 kg ball thrown with a speed of 16 m/s.

What then happens to the girl?

## Homework Equations

Momentum = mass x velocity

or

p1 + p2 = (3 m/s) m <----(p is a symbol for momentum)

or

mv1 + mv2 = (3 m/s) m

or

v1 + v2 = 3 m/s

(ONLY 1 needs to be applied...not sure which one)

## The Attempt at a Solution

I need help applying one of the formulas provided above to the question provided. I've tried a couple of these formulas already myself and the answers I got at the end I couldn't relate to the question thus I suspect none of these formulas might be useful in finding the answer, but these are the formulas I've been provided with to answer this question.

Also, aside from the formula dilemma, I found that slippery ice has no friction, so do be mindful of that if you'll be attempting this equation with me.

I guess the first question I need answered is which formula to use to answer this question if I am to use one of the provided formulas

Thanks in advance, whoever you are.
