Questions & Step-by-Step Solutions

A 4 kg object is moving at 6 m/s. If it collides with a wall and comes to a stop, what is the impulse experienced by the object?
  • Impulse – Impulse is the change in momentum of an object when a force is applied over a period of time.
  • Momentum – Momentum is the product of an object's mass and its velocity, and it is conserved in isolated systems.
  • Change in Velocity – The change in velocity is calculated as the final velocity minus the initial velocity.
