Questions & Step-by-Step Solutions

A 2 kg object moving at 10 m/s collides with a 3 kg object at rest. What is the total momentum before the collision?
  • Momentum – Momentum is the product of an object's mass and its velocity, and it is a vector quantity.
  • Conservation of Momentum – In a closed system, the total momentum before a collision is equal to the total momentum after the collision.
