A rabbit runs across a parking lot on which a set of coordinate axes has, strangely enough, been drawn . The coordinates (meters) of the rabbits position as functions of time t (seconds) are given by
`x = 0.31t^2 + 7.2 t + 28`
and `y = 0.22 t^2 - 9.1 t + 30`
(a) At t =15 s , what is the rabbits position vector `vecr` in univector notation and in magnitude - angle notation ?
