In this problem, we have that:
The reflected laser beam was observed by the astronomers 2.52 s after the laser pulse was sent. This means that .
If the speed of light is 3.00 times 10^8 m/s, what was the distance between the astronomers and the moon?
We have that m/s.
We have to find d. So:
The distance between the astronomers and the moon was meters.
