Circular Motion Regarding Car Sliding on a Curve

AI Thread Summary
The discussion centers on calculating the maximum speed a car can maintain on a level curve of 100 meters without sliding, given a coefficient of static friction of 0.70. Participants emphasize the importance of using the correct equations, particularly the relationship between frictional force and centripetal force. The solution involves recognizing that mass is irrelevant in this scenario and applying the appropriate formulas to find the answer. The final calculated speed is 26.2 m/s. Additionally, there is a request for assistance on a related assignment about the physics of drifting.

Homework Statement


What is the maximum speed at which a car can negotiate a level curve of 100m without sliding if the coefficient of static friction is .70?


Homework Equations


Ffr≤ coefficient of frictionFn
F=ma
Fc=mv2/r
Cir.=2pir
I know there are a couple more, but I'm not sure which ones.


The Attempt at a Solution


I know mass is not a factor here.
I think I'm supposed to plug in a formula into another formula. I'm thinking to plug in the force of friction formula(first formula) into F=ma.

Yup, that would work. And here's a couple of questions to help you along:

1. What else is Fn eqivalent to? (If you have to, draw a force diagram to help figure this out.)
2. What is a, given that the car is moving in a circle as it moves around the curve?
 
Ah, thank you so much. I got the right answer, 26.2 m/s.

Ok. I'm doing a small assignment about drifting at the moment! I can see that you figured out something, that might be similar to drifting.

My assignment is as following:

Describe some aspects of the phenomena drifting you'll find interesting, being a requirement that you use math, and or physics to explain.

Could you guys maybe help me out a little bit on this one?
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
