Umm not really, doesn't r= l sin theta. So how does the weight of the occupant affect r.? :)

Ok thank you so much, I think I can finish it now. :)

Thanks so much this has been the biggest help! Also how could I show that a heavier person will swing out at a greater angle than a small child if the equation cuts out mass. Does that mean that the weight won't affect the angle swung.?

Cool thanks. :) That's the situation, the full questions are in a chair-o-plane 1. will a child swing out at a greater angle than a much heavier adult? 2. Will people on the inside swing out at the same angle as those on the outside? 3. Will empty chairs be a problem? and 4. What will happen as...

So is that expression for the angle swung?

Yeah, is that vertical or horizontal.?

Homework Statement By resolving forces horizontally and vertically and using Newton's second Law, find an expression for the angle swung out of a Chair-o-plane ride. Im just not really sure how to resolve the forces vertically and horizontally. Homework Equations So far I know that...

R= ( V^2 *sin (2* (90- theta)) / g. << is that what you mean by use brackets or is it wrong altogether? :) And if it is right if the angles are complementary that R= ( V^2 *sin (2* (90- theta)) / g and R= ( V^2 *sin (2* theta) / g should equal the same range shouldn't they? Or am I completely...

Oops that's not suppose to be there. Do you have any suggestions on how I could go about proving that that equation is the same as- R= (V^2 * sin 2* 90- theta ) / g Also is it suppose to be on gravity or on acceleration? Thanks heaps for everyone's help :)

Ok umm so should R = (Vx) (t) With Vx= (Vcos theta) and t= (2*Vsin theta)/g So R should = (-V^2 * sin2 theta)/g Is that part right?

So the vertical = (u sin theta) t Horizontal = (u cos theta) t -4.9t^2 Depending on the angle would depend on what time is when it hits the ground, wouldn't it.?

Ok I'll try. No I don't have an expression. I really don't have anything other than what's in my question is all I know really.

Homework Statement I have an assignment that is to prove for instance the range of a projectile that is fired from 40 degrees will be the same as one fired from 50 degrees cause they are complementary but I need a general way to prove it for all angles less than 90 degrees.Homework Equations...
