    Block Dynamic
AI Thread Summary
The discussion centers on a physics problem involving two blocks with different masses and friction coefficients. The user seeks assistance in determining the acceleration of the bottom block and the maximum force that can be applied before the top block slips. They express uncertainty about how to approach the problem, particularly in drawing free body diagrams and applying Newton's second law. Other participants encourage the user to share their attempts to solve the problem for more targeted help. The conversation emphasizes collaborative problem-solving in physics.

I was wondering if anyone knows the answer to this question:

Homework Statement



consider 2 blocks of masses m1 and m2. the block of mass m1 is resting on top of the block m2 which in turn is resting upon a horizontal surface. The coefficient of static friction between the 2 blocks is u1 and the coefficient of the kinetic friction between the lower block and the horizontal surface is u2. A force, F, is being applied to the bottom block at angle0 to the horizontal, and the 2 blocks are moving together in the horizontal direction.

Homework Equations



a. Draw a free body diagram (Best if drawn, but I think I can still manage without it)

b. write equations representing Newton's 2nd law for each of the above diagrams. For each diagram add equation(s) representing the relationship between frictional and normal forces

c. wut is the acceleration of the bottom block?

d. What is the maximum force, F max, that can be applied before the top block slips?


The Attempt at a Solution



No idea...

Thanks a lot for the help!

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...
