**1. Homework Statement**

Mass m1=6kg traveling with velocity 4 m/s collides with mass m2=16kg traveling with velocity 3m/s in the direction shown (m2= is at an angle of 60degress). If the two masses stick together, find the final velocity of the combined masses, and the kinetic energy lost.

**2. Homework Equations**

m1v1+m2v2/m1+m2 , 1/2mv^2

**3. The Attempt at a Solution**

I tried equating 1/2mv^2= m1v1+m2v2/m1+m2 i tried finding the momentum and equate it with the KE but is no the right set up. I trying to come up witht he right set up but thisis the lonly thing that is poping in my head. I'm trying to find the velocity of the combined masses but they cannot be the sum of the masses v=2m i don't know what i'm doing. Help?
