## Juggler Issue

Science brain teasers require understanding of the physical or biological world and the laws that govern it.

 Puzzle ID: #44177 Fun: (2.63) Difficulty: (1.37) Category: Science Submitted By: rockstar1234567

A juggler must perform a trick in which he crosses a narrow bridge juggling 3 balls. He weighs 80 kg and each one of the balls weighs 10 kg. However, the bridge can hold only 100 kg before breaking. The lion tamer said that as long as he kept one ball in the air, the bridge won't collapse. Is he correct?

Every action has an equal and opposite reaction. In fact, the lion tamer was wrong. Since each ball weighs 10 kg, it takes more than 10 kg to throw a ball into the air. Add that to the weight of the juggler and the weight of the balls he is holding, and the total will be over 100 kg. Therefore, the bridge he is standing on will collapse.

 Nerine Feb 25, 2009 Good one!! Knew the 3rd law, guessed that the lion tamer was wrong but couldn't put it into words... Yay for SCIENCE!! braingle100 Feb 25, 2009 poor juggler. megabreath Feb 25, 2009 Poor bridge. ttt3142 Feb 25, 2009 What's under the bridge, anyways? megabreath Feb 26, 2009 Well the juggler is now. tamjp Feb 26, 2009 ditto what Nerine said entertaining visual imagery made a dry scientific teaser fun thanks tamjp Feb 26, 2009 perhaps the lions are under the bridge wisteriastorm Feb 28, 2009 I got it without the hint, but i said that when he catches the ball the force would cause him to go over the weight limit.(i'm thinking thought that could be disputed, therefore making yours more accurate =]) great teaser AndrewWalker Mar 07, 2009 easy but great teaser! Shadows Mar 09, 2009 I can't believe it took six years for this to be submitted. It's almost a classic! Right now, I'm trying to picture an 80 kg fatso juggling bowling balls. I have to try juggling those sometime . . . (user deleted) Mar 18, 2009 I think it's a toss-up. If the ball weighs 10 kg and it takes another 10 kg to catch it and return it to the air, that's right at the 100 kg limit. Our juggler has a slim chance (but he better keep going) Deedee123 Apr 01, 2009 Who makes a bridge w/ only a 100 kg limit? Deedee123 Apr 01, 2009 And who weighs 80 Kg? Paladin Apr 09, 2009 Scientifically found teaser and correct answer. Very fun! bradon182001 Apr 19, 2009 Interesting teaser. I'll have to take your word for the answer, though. Thanks for posting. (user deleted) Jun 16, 2009 What about the force from him propelling himself forward on the bridge and moving one arm up to throw up the next ball. If he is moving at all, at no point will the force from his 80 kg be applied to the bridge right? UptheHill Aug 06, 2009 Nice one, keep them coming!!! skuxdux Sep 02, 2009 ummm it was kind of boraang doctapeppaman Aug 28, 2010 The average male weight in the United States is actually over 80kg. JQPublic Sep 28, 2010 It's hope the juggler either doesn't listen to the lion tamer or loses weight! lyckzx Dec 07, 2010 I got ur point eventhough it's quite confusing..i suggest you put ur computations on how u come up on ur conclusion..& oh, let me remind u that kg is only a unit for weight & not for force..anyways, it's still a good teaser..keep it up!.. AgKKR20 Mar 04, 2011 Easy one...got that right in the first attempt...but thanks for submitting... SRB_1807 Oct 14, 2011 good one man .... marcuslikespie Aug 27, 2012 What if he juggled nearly straight horizontal? I juggle that way sometimes, and I don't think the force to throw would affect the bridge. RICHARDYAMA Sep 17, 2016 Ummm, there has been billions of people throughout history weighing 200 kilograms(kg). One kg = 2.2 pounds. 80kg x 2.2 = 176 pounds.
