The Moon orbits the Earth in an approximately circular path. The position of the Moon as a function of time is given by
x(t) = r cos(ωt)
y(t) = r sin(ωt),
where r = 3.84 10^8 m and ω = 2.46 10^-6 radians/s. What is the average velocity of the Moon measured over the interval from t = 0 to t = 3.54 days? Find its magnitude, in m/s, and find its direction, given as an angle measured counterclockwise from the positive x-axis.
magnitude _____m/s
direction _____° counterclockwise from the +x-axis
