An ant, crazed by the Sun on a hot Texas afternoon, darts overan xy plane scratched in the dirt. The x and y components of fourconsecutive darts are the following, all in centimeters: (30.0,38.0), (bx, -68.0), (-23.0, cy), (-83.0, -68.0).The overalldisplacement of the four darts has the xy components (-140,-19.0).What are (a) bx and (b) cy? What are the (c) magnitude and(d) angle (counterclockwise from the positive direction of the xaxis) of the overall displacement?
