Will the Cyclist Skid Around the Turn?

AI Thread Summary
The discussion centers on whether a cyclist traveling at 10 m/sec can successfully navigate a 20 m radius turn without skidding, given a weight of 60 kg and a coefficient of static friction of 0.2. The maximum speed calculated for safe turning without skidding is 6.2 m/sec, indicating that the cyclist will skid since their speed exceeds this limit. The conversation also touches on the importance of using proper language, noting that "cyclist" should be referred to in the singular form. Overall, the analysis confirms that the cyclist will skid into a crash due to exceeding the safe speed limit.

Will The cyclist Skid??

Can someone tell me if I have done this right. The question I am working on is...

A cyclist is going 10m/sec around a 20 m radius turn. If they weight 60kg and the coefficient of static friction is 0.2, will the make the turn or skid into a crash??

I found the maximun speed the cyclist could go around the turn without skidding and got 6.2 m/sec. Then I assumed that becasue it was slower then what the cyclist was traveling they would skid when going around teh turn.

Have I done this right or should I have gone a different route in doing this?

Looks good to me Woody, although I'm pretty pissed and it's late.
 
You're correct, but use standard written English next time. A cyclist is a single person, therefore you wouldn't refer to him as "they."
 
Thats right.

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...
