A 20 kg shopping cart moving at a velocity of 0.5 m/s collides with a store wall and stops. The momentum of the shopping cart

decreases?

  • physics - ,

    yes; the momentum becomes zero. That is a reduction

  • physics - ,

    what would it mean if i say
    the momentum is conserved?

  • physics - ,

    It is irrelevant to the question. The momentum of the cart is not conserved, because a force of impact is applied to it. The momentum of the cart PLUS wall is also not conserved, because of stress forces applied at the base of the wall.

  • physics - ,

    ok, i was just wondering since that was one of my choices


    thanks
