Homework Help: Inelastic Collision of a car

  1. Oct 18, 2011 #1
    1. The problem statement, all variables and given/known data

    A blue car with mass mc = 499 kg is moving east with a speed of vc = 21 m/s and collides with a purple truck with mass mt = 1283 kg that is moving south with a speed of vt = 11 m/s . The two collide and lock together after the collision.

    What is the angle that the car-truck combination travel after the collision? (give your answer as an angle South of East)

    2. Relevant equations


    3. The attempt at a solution

    I am not really sure how to set this problem up. I understand that they will stick together and that the momentum will be conserved. I also understand that this problem will require breaking it down in to move along the x and y axis but how do start.

    along x:
    mass of truck (velocity) +mass of car(velocity)=(mass of truck and car)(vx)
    . solve..

    along y:
    mass of truck (velocity) +mass of car(velocity)=(mass of truck and car)(vy)


    Love answering my own questions.
