  1. Sep 27, 2011 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    I already got the first part (v_b/a) i need to find r dot and theta dot

    3. The attempt at a solution
    well i got v_b/a. for r I was thinking of using sqrt(y^2 +x^2) at the r and taking derivatives of that. i dont quite understand polar coordinates
