A 1500 kg car traveling at 17.6 m/s to the
south collides with a 5000 kg truck that is
initially at rest at a stoplight. The car and
truck stick together and move together after
the collision.
What is the final velocity of the two-vehicle
mass?
Answer in units of m/s

  • Physics -

    momentum before = (1500) 17.6

    momentum after = (1500+5000) v

    momentum after = momentum before

  • Physics -

    So basically 1500 * 17.6?

  • Physics -

    huh?
    (1500)17.6/(1500+5000)

  • Physics -

    when the little car hits the stationary big truck, it slows down.

  • Physics -

    Yes, I got it. Thank you
