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. If the speed of light is 3.00x10 m/s, what was the distance between the astronomers and the moon?

D) 2376 m/s 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. If the speed of light is 3.00x10 m/s, what was the distance between the astronomers and 10) the moon? A) 3.78x10 m B) 37800000 m 8.40x10 m D) 8.40x10 if you were the first Mars explorer and discovered that when you dropped a hammer if took 0.68 s to fall 0.90 m to the ground, what would you calculate for the gravitational acceleration on Mars? 11) A) 4.32x 10 m/s
