3. (25 Points) This problem is continued in Problem 4. Two robots are placed at rest in the horizontal x,y plane: robot #1 at the point (AB) and the robot #2 at the point (C,D). At t = 0 they begin to move. The rst robot moves with a constant, known acceleration of magnitude k, for a known amount of time to seconds, along the line at the known angle 9 shown below. After to seconds it has zero acceleration. Find its x and y coordinate; at the time t = to and its x coordinate as a. function of time for any time greater than to. Y UM?) . (CID) \f
