Curvilinear (n/t) motion (find magnitude of acceleration)

AI Thread Summary
The discussion focuses on calculating the magnitude of acceleration in curvilinear motion, specifically using the formula that combines normal and tangential acceleration. The user successfully calculated normal acceleration but struggles with determining tangential acceleration. They attempted to find tangential acceleration by using distance and time derived from angular motion but arrived at an incorrect answer. The user has been working on the problem for several hours and seeks assistance to resolve the issue. Clarification on the calculation methods for tangential acceleration is needed to achieve the correct result.

pls see the attachment. so pretty much magnitude of acc would be root (at2 + an2). i figured out an by subbing it into v2/p. but i can't figure out how to calculate at!

id really appreciate the help, I've been at it for 3 hours now! thanks!

ok let me show my working:

normal acc = 0.009^2/0.066

tangential acc i tried this:

s=r theta
s = 0.066 times (66/180)*pie
s = 0.07603
v = d/t
t = d/v
t = 0.07603/0.009
t= 8.4477 seconds

therefore acc = v/t
acc = 0.09/8.4477

then i squared this and the normal acc, but its not the right answer
 

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'

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...
