Question

During an Apollo moon landing, reflecting panels were placed on the moon. This allowed earth-based astronomers to shoot laser beams at the moon's surface to determine its distance. The reflected laser beam was observed 2.52 s after the laser pulse was sent. The speed of light is 3.0 × 108 m/s. What was the distance between the astronomers and the moon?

Answer 1

Explanation:

you can use the formula speed=distance /time

distance=speed×time

distance=3.0×108m/s×2.52s

distance=816.48m/s^2
