A 3 kg mass moves at 1.5 m/s and collides elastically with a 2 kg mass that is at rest. Determine the velocity of the 2 kg ball after the collision.
Added by Kristine N.
Step 1
Momentum is defined as the product of mass and velocity, so the momentum of the 3 kg mass is: Momentum = mass * velocity = 3 kg * 1.5 m/s = 4.5 kg·m/s Since the 2 kg mass is at rest, its initial momentum is zero. During an elastic collision, Show more…

A $0.50-\mathrm{kg}$ ball that is traveling at $6.0 \mathrm{m} / \mathrm{s}$ collides head-on with a $1.00-\mathrm{kg}$ ball moving in the opposite direction at a speed of 12.0 m/s. The 0.50-kg ball bounces backward at 14 m/s after the collision. Find the speed of the second ball after the collision.
