Calculate displacement [Two Dimensional Kinematics]

  1. Jun 12, 2013 #1
    1. The problem statement, all variables and given/known data
    A skidding car starts moving with a velocity of 6.75m/s at an angle of 58.82657 degrees north of east. Its velocity just before it comes out of its skid 4 seconds later is 3.25 m/s at an angle of 49.6091 degrees south of east. It travels with a constant acceleration while it is in the skid. What was the car's displacement


    2. Relevant equations
    None really imo.


    3. The attempt at a solution
    I took apart both vectors and figured out the components.

    After that I inserted the variables into x-xi=1/2(v+vi)t

    After I got the answer for both the x and y values. I put the answers from polar form into cartesian form. My final answer is 14.73222776m. Did I get this right? Because honestly, I think I'm approaching this problem in a wrong way.

    without working through the problem I can say that I don't think it should have that many sig figs in it.
