Rotational Kinematics Problem Interpretation

AI Thread Summary
The discussion revolves around interpreting a rotational kinematics problem related to a car's braking. The initial scenario involves the wheels locking after 2.0 revolutions when the brakes are applied. The key question is how many revolutions occur if the initial speed is doubled, while maintaining constant acceleration. Participants emphasize the importance of understanding the relationship between initial speed and the number of revolutions before stopping. Writing out the problem helps clarify the connection between these elements, leading to a better grasp of the solution.

Homework Statement


If you step on your car's brakes hard, the wheels stop turning (i.e., the wheels "lock") after 2.0 revolution.


Part A.
At the same constant acceleration, how many revolutions do the wheels make before stopping if your initial speed is twice as high?


Homework Equations


Rotational Kinematics
Omega
Alpha
etc...


The Attempt at a Solution


I need help interpreting the problem not doing it.



Ok, the first part says it took 2 revolutions to startup.
The actual question is asking me how many revolutions are made though. How are these two parts related?

Figured it out. It's amazing how writing things out always puts it in perspective.
 

Thread 'Errors and significant figures'

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...
