Homework Help: I have a test tomorrow can someone please help me with this vector problem?

    1. The problem statement, all variables and given/known data
    If a car has an initial velocity of 8.0m/s, 25degrees and turns in 4.0 s so it ends up traveling at 11.0m/s, 140degrees find:
    a)the acceleration
    b)the displacement for the 4.0 s

    Have a go at it and then come back.

    ok I will try but I hardly know where to start

    a)

    V1-8.0m/s, -25degrees
    V2-11.0m/s,-140degrees
    acceleration-
    displacement-
    time-4.0s

    eq.V2=V1+a*t
    11.0m/s,-140degrees=8.0m/s, -25degrees+a*4.0s

    now Im not sure if this is how you would start this can someone steer me in the right direction?
