an astronaut on the surface of the moon fires a cannon to launch an experiment package, which leaves the barrel moving horizontally. Assume the free-fall acceleration on the moon is one-sixth of that on the earth.

(a) what must the muzzle speed of the package be so that it travels completely around the moon and returns to its original location?

(b) what time interval does this trip around the moon require?
