Distance traveled by block attached to cylinder

AI Thread Summary
The discussion centers on calculating the distance traveled by a block attached to a cylinder, given an angular acceleration of 70.03 rad/s² and a mass of 0.47 kg. The user seeks assistance in determining the distance traveled between 0.51 seconds and 0.71 seconds, acknowledging the need to find the total distances at both time intervals. It is suggested that the angular form of displacement for constant acceleration should be used, and the user is reminded to subtract the distances at the two time points to find the distance traveled in that interval. The user expresses confusion about finding the initial velocity needed for the displacement equation. Clarifying the entire problem is recommended for better assistance.

Ok so i found the angular accleration when the block of the mass is attached to the cylinder to be 70.03 when the mass weighs .47 kg. But i am having trouble finding the distance it has traveled from 0.51 s to .71 s assuming that at 0s the motion has begun. Does anyone have any ideas?
 
Physics news on Phys.org
If the angular acceleration is constant, use the angular form of displacement for constant acceleration. The distance between 0.51s and 0.71s is the difference between the total distance traveled in 0.51s and 0.71s
 
i understand that you should find the distances of each time and subtract to find the distance traveled within that time but I don't understand how to find the velocity because the equation to find displacement requires aninitial velocity.
 
State the entire problem then
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
