Elastic collisions help?
So i'm quite confused regarding this.
""""""""""Sphere 1, travelling at velocity u1, undergoes an elastic collision with a stationary sphere of equal mass and radius (sphere 2). Show that, after the collision, sphere 1 has speed |u1|cos(theta) and sphere 2 has speed |u1|sin(theta), where q is the angle through which sphere 1 is deflected. Assume both spheres are smooth.""""""
I thought that as they are the same mass there would be no angle? And it would just be perpendicular? Really have no clue to go about this question.
Man i'm just really not understanding which ones are at an angle. I thought only the ones in 2d that are unequal masses

I think i can work it out if i just understand what this formula means: SIN THETA=DELTA/2R for Point of Impact. I'm just not sure what delta would be.
