Don't get scared when you hear the word Physics!

A 1500 kg car traveling at 16.0 m/s to the
south collides with a 5100 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 -

    The direction of the car&truck, stuck together, remains south.

    For the final speed Vf, use the conservation of momentum law

    Initial momentum = Final momentum
    1500*16.0 = 6600*Vf

    Vf = 3.63 m/s
