What is the Magnitude of Acceleration in the n Direction?

AI Thread Summary
The acceleration in the n direction is determined to be 18 m/s², which is identified as centripetal acceleration. This value is derived by applying the centripetal acceleration formula in the context of net force. The discussion emphasizes understanding how centripetal acceleration relates to overall acceleration in motion. Clarification is provided through reference to an accompanying image that illustrates the calculations. The explanation highlights the importance of correctly applying formulas to solve for acceleration in physics problems.

I think your question is answered in the second image, in the text above. It's simply plugging the centripetal acceleration into the equation for net force. :P
 

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...
