A rabbit runs across a parking lot on which a set of coordinate axes has, strangely enough, been drawn. The coordinates (meters) of the rabbit’s position as functions of time t (seconds) are given by x=-0.31t2 + 7.2t + 28 (4-5) and y =0.22t2 - 9.1t + 30. (4-6) (a) At t = 15 s, what is the rabbit’s position vector in unitvector notation and in magnitude-angle notation?

Question
A rabbit runs across a parking lot on which a set of
coordinate axes has, strangely enough, been drawn. The coordinates
(meters) of the rabbit’s position as functions of
time t (seconds) are given by
x=-0.31t2 + 7.2t + 28 (4-5)
and y =0.22t2 - 9.1t + 30. (4-6)
(a) At t = 15 s, what is the rabbit’s position vector in unitvector
notation and in magnitude-angle notation?
