A 4 kg ball rolling to the right with a velocity of 26 m/sec collide with a 6 kg ball rolling to the left moving with velocity of 14 m/sec. If the collision is perfectly elastic, determine the velocity of each ball after the collision.
Added by Pedro D.
Step 1
The total momentum before the collision is the sum of the momentum of the 4 kg ball and the momentum of the 6 kg ball. Momentum of the 4 kg ball = mass x velocity = 4 kg x 26 m/sec = 104 kg m/sec to the right Momentum of the 6 kg ball = mass x velocity = 6 kg x Show more…
