Two cars, one of mass 1300 kg, and the second of mass 2200 kg, are moving at right angles to each other when they collide and stick together. he initial velocity of the first car is 14 m/s in the positive x direction and that of the second car is 18 m/s in the positive y
direction.
What is the magnitude of the velocity of the
wreckage of the two cars immediately after the

  1. Have you tried to do all these problems or do you just think I need the practice?

    momentum after = momentum before
    momentum is a vector
    so
    momentum in the x direction after = momentum in the x direction before
    and
    momentum in the y direction after = momentum in the y direction after.

    mass is conserved. Total mass after = total mass before
