Homework Statement
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?
Homework Equations
mv+mv=mv+mv
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
