Ok, thank you for your replies. Chet, I appreciate your help here. My initial calculations to this question were exactly as you have described as the gravitational element was the only factor which, logically, was a downward producing force in this formula. Then when I mentioned the problem...

I agree there can be more variables to consider such as tyre rubber compound effect on tarmac, whether the circular course is banked etc. Using the information provided it appears there is no option, in lack of evidence otherwise, than to assume the CofF is equal between the two cars. Am I...

That's a fair point and yes I would expect this would have an effect on increasing the coefficient of friction between tyre and tarmac but the question did state the coefficient was constant, which is why this has baffled me!

Correct Steam King, the standard car in this example doesn't have the extra downforce enhancements and it is possible the coefficient of friction will be the same between the tyres and tarmac on both vehicles. However, with the given formula, I could only see the coefficient of friction as...

Homework Statement Hi, (firsly apologies for posting in wrong area originally) I'm new to the forum and this is my first post...so go easy! I have a physics problem to solve and if possible I would love a bit of help here. This is the question: A standard car is driven around in a measured...

Hi, I'm new to the forum and this is my first post...so go easy! I have a physics problem to solve and if possible I would love a bit of help here. This is the question: A standard car is driven around in a measured circle, increasing its speed as it goes and is able to reach 85mph before it...
