After a completely inelastic collision, two objects of the same mass and same initial speed move away together at half of their initial speed.
(a) Find the angle between the initial velocities of the objects
∑pxi = mvi
∑pxf = 2mvfcosӨ
mvi = 2mfvcosӨ
∑pyi= mvi
∑pyf = 2mvfsinӨ
mvi=2mvfsinӨ
2mvfsinӨ = 2mfvcosӨ
1= sinӨ/cosӨ
1=tanӨ
Ө=45°
I feel like there's something I'm not doing right in this problem. Can anyone point out any mistakes?
