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

Light that is polarized along the vertical direction is incident on a sheet of polarizing material. only 96% of the intensity of the light passes through the sheet and strikes a second sheet of polarizing material. no light passes through the second sheet. what angle does the transmission axis of the second sheet make with the vertical?
