# How fast could a stone be thrown using a sling while standing on the moon?

Similar to this question except not about using a machine: What payloads and launch speeds could a sling launcher get using modern materials on the Moon?

How fast could a stone be thrown using a sling while standing on the moon? Could you launch a rock into lunar orbit with a very long slingshot? Google has nothing about this.

Edit: I only said 'of the type whirled around above the head' to clarify that I didn't mean a catapult. Don't assume that that the solution needs to involve anything whirling above the head.

• Orbital Velocity of the Moon is 1.03 km/s. There's no way a human could throw something at 1.03 km/s – Star Man Apr 20 at 16:53
• I think this depends on how heavy your rope material is – BrendanLuke15 Apr 20 at 17:33
• The same speed as it could be thrown anywhere else? There's no "g" in omega x r. – Organic Marble Apr 20 at 18:03
• Your initial velocity depends only on your slingshot force and that will be the same as on earth. So the projectile should launch at the same speed, only difference being it does not decelerate due to drag and it arcs less due to gravity. But, if the slingshot is the same on the moon as on earth, I would expect to see absolutely no difference in your starting velocity. – user39728 Apr 21 at 16:48
• @OrganicMarble So did I. If you use motors, bearings etc, air resistance stops being the ultimate limiting force, and the next threshold: that of your device ripping itself apart, will be mostly the same on Earth and on the Moon. – SF. Apr 23 at 5:46
