High school physics basic question about two dimensional motion (WITH PICTURE)

  1. Sep 26, 2008 #1
    Stuck on this problem.

    I think acceleration is about 0.4m/s^2, but having the worst time trying to find direction. I think the sine or cosine law is supposed to be used?? Here's the question:

    Welcome to PF.

    I think you will need to treat your acceleration here as the difference of the vectors of velocity divided by time. This would mean that you need to resolve each of your velocities into its x,y components and then take the difference. This will give you a resulting velocity vector that when divided by the scalar of time should yield both the average acceleration (the magnitude) and of course the direction.
