A laser beam aimed from the earth is swept across the face of the moon.

a)If the beam is rotated at an angular velocity of 1.30×10?3rad/s, at what speed does the laser light move across the moon's surface?

b) If the diameter of the laser spot on the moon is 6.15km , what is the angle of divergence of the laser beam?
