Homework Statement
After a completely inelastic collision, two particles of the same mass m and same initial speed v are found to move away together with the speed (2/3)v. Find the angle between the initial velocity vectors of the objects.
The Attempt at a Solution
It is completely inelastic which means the two objects stick together and share the same final speed. Energy is not conserved but Momentum is so
mv + mv = (m+m)V
2mv = 2m(2v/3)
2mv=4mv/3
2=4/3
I definitely did something wrong here
