How far away is the Moon at apogee if a reflected beam of light takes 2.70
seconds to travel from Earth to the Moon and back? The speed of light is
c=3x108 m/s. (Hint: You need to use the definition for the average speed of an
object and DON’T FORGET THAT THE TIME GIVEN IN THE PROBLEM
IS THE TIME THAT THE BEAM OF LIGHT TRAVELS TWICE THE
DISTANCE FROM EARTH TO THE MOON.)

    The moon's distance from the earth is ~ 3.84 × 108m. A laser pointer is mounted on a turntable such that its beam repeatedly sweeps over the surface of the moon. If it rotates at a period of 4s, prove that its impact spot travels across the moon at about twice the speed of light. Why does this not violate the law that nothing can travel faster than the speed of light?
