Particle Angular Velocity Problem

AI Thread Summary
The discussion revolves around calculating angular velocity from a given graph at specific time intervals. The user successfully determined the angular velocity at t=1s as 0 but struggles with calculations for t=4s and t=7s. They question the validity of the equation ω = θ/t and express confusion over using 2π radians/T for their calculations. Additionally, there is a request for guidance on finding velocity from a position vs. time graph. The conversation highlights the challenges of applying angular motion equations in practical scenarios.

Homework Statement



I am given this graph and asked to find:
a. the particle's angular velocity at t=1s
b. angular velocity at t=4s
c. angular velocity at t=7s

Homework Equations



ω = θ/t

The Attempt at a Solution



I got 0 for a, which is the correct answer. However, I cannot seem to figure out b or c. For c, I got 2π/7 and it is incorrect. I've also tried 2π*radians/T and that doesn't work either. I'm not really sure what to do.

are you sure ω = θ/t is the right equation?

how do you find velocity on a graph of position vs time?
 
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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is(Figure 2): F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
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...
