## Homework Statement

You are standing on a large sheet of frictionless ice and are holding a large rock. In order to get off the ice, you throw the rock so it has velocity relative to the Earth of 11.3 m/s at an angle of 34 above the horizontal. Your mass is 67.0 kg and the rock's mass is 14.4 kg.

**What is the magnitude of the impulse on the Earth as a result of this throw?**

## Homework Equations

p=mv

J = p_2 - p_1

## The Attempt at a Solution

The first part of the question had me find the speed of me after the throw.

m

_{me}v

_{me}= m

_{rock}v

_{rock}

67(v) = 14.4(11.3cos34)

v= 2.01 m/s

Now i am asked to find the impulse as stated above.

I thought the impulse would just be zero since momentum of this is conserved but i was wrong.

Can anyone help me with this please?

Thank you :)
