1. The dog runs across the backyard lot on which a set of coordinates axes has, strangely  observed, been drawn. The coordinates of the dog’s position as functions of time t are given  by  X = -0.35?2 + 7.5t +30  and  Y = 0.25?2 – 9.5t + 26. With t in seconds and x and y in meters. (a) At t =15.0s, what is the dogs position vector ? in unit – vector notation and as magnitude  and an angle.
