    Blocks Speed
AI Thread Summary
To find the speed of blocks A and B after moving 2.70 cm, one can apply Newton's laws and consider the forces acting on both blocks, including gravitational force and friction. The kinetic friction between block A and the tabletop plays a crucial role in determining the net force and acceleration of the system. Using energy methods or kinematic equations can also help in solving for the final velocity after the specified distance. The discussion highlights the importance of understanding velocity beyond circular motion, as it is a fundamental concept in various physics problems. A clear setup of the problem is essential for accurate calculations.

As shown in the figure , block A (mass 2.20kg ) rests on a tabletop. It is connected by a horizontal cord passing over a light, frictionless pulley to a hanging block B (mass 2.27kg ). The coefficient of kinetic friction between block A and the tabletop is 0.344.

After the blocks are released from rest, find the speed of each block after moving 2.70cm

Asking for V.

And I am so confused since we only only use V in circular motion, So I don't even know how to set it up

Are you familiar with energy methods, Newton's laws, and / or the kinematic equations?? The velocity or speed is used quite often in Physics problems, so surely you must have seen it other than in circ motion problems, is that right??
 

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...
