a 10 kg ball moving due west at 2m/sec collides with a 4kg ball that is moving due east at 3 m/sec. You determine that immediately after the collision the 10 kg ball is moving due west at 0.57 m/sec.
A) this probably IS a Totally inelastic collision
B) this definitely is NOT a Totally inelastic collision
