## Homework Statement

two particles of masses m

_{1}and m

_{2}move at speeds u

_{1}, u

_{2}respectively collide and fuse. If α is the angle between the two directions of motion before the collision, find an expression for the new mass m, in terms of m

_{1}m

_{2}u

_{1}u

_{2}and α

However this does not take into consideration the angle α, so I am unsure as to where this comes in.
