    Force and acceleration given position equations. Find magnitude and angles

    Homework Statement A 0.42 kg particle moves in an xy plane according to x(t) = - 19 + 2 t - 2 t3 and y(t) = 25 + 8 t - 7 t2, with x and y in meters and t in seconds. At t = 0.6 s, what are (a) the magnitude and (b) the angle (within (-180°, 180°] interval relative to the positive direction of...

    Vector addition. finding x & y components, the magnitude, & the angle

    thanks. i figured it out. i needed to use 140 for theta 2 (108+32). because B's angle was 108 plus the 32
