(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A child throws, at 10 m/s, a 3.4 KG package, horizontally, from a boat. The boat weighs 60 kg and the child weights 20 kg. If the boat was initially at rest, what was it's speed, after the throw?

2. Relevant equations

mv+mv=mv+mv

3. The attempt at a solution

I am not sure, do you have to add in the boat and child weight together so it is

mv+mv=mv+mv

0+0=(3.4)(10)+(20+60)v

v=-.425
