(adsbygoogle = window.adsbygoogle || []).push({}); 1. a 9.0 killogram mass and a 3.0 kg mass are at rest on a frictionless table. A massless spring is compressed between the masses, which are held together by a thread. The thread breaks and the 9.0 kg mass moves to the left with a velocity of 2.0 m/s. Find the velocity of the 3.0 kg mass.

2, m1v1+m2v2=(m1+m2)v3

3. 9(2)+3

18+0=12v3

v3=1.5m/s

this was my original attempt, but i realize it is not solving for the velocity of the 3.0kg mass but i don't know what else to do

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
