Please help me with vector acceleration problem

  1. Oct 9, 2006 #1
    I'm having trouble with finding V2 using the vector diagram I'm given.
    I know the equtaion I have to use is V2 = delta velocity + V1

    Here's a description of the diagram.
    I have the V1 vector going up 3cm at an 80 degree angle. The change in velocity is 5.1cm down at 90 degrees. And the scale I'm given is 1cm = 1km.

    I drew the two vectors togther on one diagram, but I don't know what to do next. Can someone help me please?
