AI Thread Summary
To solve the vector math problem involving initial velocity (vi), final velocity (vf), time (t), and acceleration (a), it's essential to clarify the task at hand, as the problem statement is incomplete. Users suggest drawing the vectors on a coordinate plane to visualize their relationships, which can help determine whether to add or subtract them. The discussion emphasizes the importance of understanding vector addition and subtraction in the context of the given angles and magnitudes. Without a complete problem statement, the specific calculation for acceleration remains unclear. Properly defining the problem is crucial for finding the correct solution.

Homework Statement


vi=35m/s (s 10 degrees w)
vf=30m/s (n 30 degrees w)
t=5.0x10^-3s
a=?

Do I add these vectors to get a resultant vector or do I subtract?

Try drawing the vectors on a coordinate plane, it will become obvious what to do after that.

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...
