Well at work today an arguement arose - me and one other person disagreed with about 12 others...and the thing is I can't seem to see how they'd be right. What I want to know is - could a man stop a helicopter taking off? The people I'm disagreeing with seem to think he could if he was strong enough to hold it down. I think that even if the man was strong enough to lift 1,000,000 helicopters above his head - no amount of strength makes him weigh more and the helicopter would just lift him off the ground. Unless the man's feet we attached to something on the ground surely there's no way he could stop the helicopter from taking off unless he had some sort of ability to make himself too heavy for the helicopter to lift. Silly I know, but I'd appreciate help - and maybe some explanation that I can give to people that would make them understand as anyway I explain it doesn't seem t oget through to them. Thanks.
