Two identical billiard balls are initially at rest when they are struck symmetrically by a third identical ball moving with velocity v0 = v0i (vector) http://session.masteringphysics.com/problemAsset/1034007/5/RW-09-66.jpg express final velocity (vf) of third ball immediately after the...

I have computed angular speed, centripetal acceleration, and torque for a uniform circular motion. What is the tangential acceleration? I am leaning towards tangential a = r(alpha) where alpha is d(omega)/dt. since I have calculated omega and a = dv/dt - I think its safe to say that as...
