A rabbit runs across a parking lot on which a set of coordinate axes has strangely enough been drawn. The coordinates of the rabbit's position as functions of time are given by
#x=(-0.31m/s^2)t^2+(7.2m/s)t+28m#
#y=(0.22m/s^2)t^2+(-9.1m/s)t+30m#
a.) At t=15s, what is the rabbit's position vector r in unit vector notation and as a magnitude and an angle?
b.) Find the velocity v at time 15s in unit vector notation and as magnitude and angle.
