1/2 [vo + (v0 + at)]t ? please explain every step

physics
1/2(v0 + v) (v- v0)/ (a) =

physics
1/2(v0 + v) (v- v0)/ (a)

physics
1/2(v0+v)(v-v0) ----- (a)

Physics
A ball of mass m1= .250 kg and velocity v01 = + 5 m/s collides head-on with a ball of mass m2= .800 kg that is initially at rest (v02 = 0 m/s). No external forces act on the balls. If the collision is elastic, what are the velocities of the balls after the collision?

I have the equation, 2 2 2 1/2 m1 Vf1 + 1/2 m2 vf2 = 1/2 m1 V01 you need to plug into the above equation Vf2 = m1(Vo1-Vf1)/m2
