## Main Question or Discussion Point

If you were riding a bike and then reached out to grab a bar over your head,

Picture the following senerio... a 50 lb kid is riding a bicycle as fast as he can toward a cloths line. Just at the moment he travels under the bar, he reaches up and grabs the bar and lets the bike go flying off. His hope is to make a complete arch around the bar in the same way a gymnast does when flipping around the bar. The question is, how fast would he have to go to have that amount of momentum to get around the bar and what would the g forces be, so he would know how strong his grip would have to be? If anyone knows how to calculate this could they show how it is calculated?

Thanks, ps not that I'm planning on trying this, I just did try it as a kid and found out it was impossible, but was curious just HOW impossible it really was.
