Nice, in terms of what I have already written in the document. Do you think that it would suffice considering that the question is only worth 6 marks? Would you say that what I have written answers the question?

I was trying to suggest a way to " address the functional dependence on m and r". Not really too sure how to do it. How would you answer this question? Not many resources on how to prove the formula at all on the internet.

@ProxyMelon Whats your thoughts on #7? How would you tackle this?

I presume that I could address the dependce on r by varying the length of the rope? And that I could address the dependence on m by varying the amount of washers thus changing the mass and the circular motion force (F). Here is a video of the experiment which may make my setup easier to...

Interesting. How do you propose I address the dependence on m and r? There are not too many resources online that show how to verify the equation without using some expensive specialised machine.

This is a good idea. The idea of using a glass tube and string came from a teacher resource online!

Just completed my experimental plan for the question above and would like some feeback on what I can improve, and how I can fix any errors in my plan? Also please do let me know what you would have done differently if you had answered this question...

This is a tad odd as there is no mention of this in my course. I suppose that what you are saying is that when when the centripital acceleration > gravitational acceleration then the person would fly off?

Trying to think of which formula I would use for this... I suppose it must angular velocity (w) and gravity (g)? Maybe the centripital force equation F=(mv^2)/r where F=0?

Thanks, this clears up a lot of my questions! What about part e? I would assume that a person would fly off Earth when gravity would be equal to 0. Therefore I must find the speed at which gravity is equal to zero? This is purely my own thoughts as there is nothing on this in my syllabus! The...

@Merlin3189 @PeroK Here are the images of the questions and my working out thusfar. Whats your thoughts on the wording of the questions? Methinks that they are not clear as they could be... Hope that this makes more sense! :)

Attempting to learn...

Aha, 7 × 10-5 is in rad/s not m/s! Does this mean that V should be the linear velocity of earth? EDIT: I think that I have it! Thank you very much!

What do you mean? I was asking where should gravity be placed in the equation that I was using? Also with a value of 100kg, (mv^2/r) is giving me 7.78x10^-14=W-R which is wrong i think? How would you work this question out?

The value should be 9.81 according to my specification. Just wondering how to include it in this equation?
