Problem Solving Strategy for Collisions 1. Set up a coordinate system and define your velocities with respect to that system. It is convenient  to have the x axis coincide with one of the initial velocities. 2. In your sketch of the coordinate system, draw all velocity vectors with labels and include all the  given information. 3. Write expresses for the  x  and  y  components of the momentum of each object before and after the  collisions. Remember to include the appropriate signs for the components of the velocity vectors.  For example, if an object is moving in the negative  x  direction, its  x -component of velocity must  be taken to be negative. It is essential that you pay careful attention to signs. 4. Now write expressions for the total momentum in the  x  direction  before  and  after  the collision and  equate the two. Repeat this procedure for the total momentum in the
