Essay

The equation $\vec { r } = 4 x \vec { i } + 4 y \vec { j } = 12 \cos ( 2 \pi / 360 ) \vec { i } + 12 \sin ( 2 \pi / 360 ) \vec { j }$ describes the motion of a particle moving on a circle.Assume x and y are in miles and t is in days.
What is the speed of the particle when it passes through the point (0, 2)?
