Comment on If you had a huge slingshot, how much rubber band would you need to send a spaceship into space?
litchralee@sh.itjust.works 3 days agoI’ve added this clarification to my comment. Thanks!
It seems that common types of rubber have a propagation speed in the range of 1.5-1.8 km/s, so we’re still quite a bit away from 10.5 km/s.
