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?
The formulas that you need to use for the final velocities can be found here:
The head-on collision case is in part "c"
