  4. 2.5 kg·m/s

Questions & Step-by-Step Solutions

A 1 kg object moving at 5 m/s collides with a stationary object. If the collision is perfectly elastic, what is the final momentum of the system?
  • Momentum Conservation – In a perfectly elastic collision, the total momentum of the system before and after the collision remains constant.
  • Elastic Collision – In a perfectly elastic collision, both momentum and kinetic energy are conserved.
