I'm sorry to inform you that those cows are going to have a hard time braking on that frictionless surface.
replyBased on a hike in the Carson National Forest 2 days ago, the only reason a cow is on a frictionless surface is that the cow shat all over it.
replyCows can't roll that fast.
replyCows don't roll - they are frictionless so just glide over the surface smoothly.
replySpherical cows on the other hand have to move with orbital velocity at least, or they fail to stay in vacuum for long and splash.
replyIt takes a stupid cow, but when they can climb mountains as they do it is not inconcievable that one can roll down.
reply(I was suprised to see a cow jumping up on a ~3m rock ledge like it was nothing)
However, they can go up stairs, but not down them.
replyOr on shabbos
