Newton's laws multiple objects contact forces

AI Thread Summary
The discussion revolves around calculating the contact forces between three crates with given masses and an applied horizontal force. The acceleration of the system is determined to be 9.85 m/s², which is consistent across all blocks due to Newton's second law. Participants emphasize the importance of drawing free body diagrams for each block to analyze the forces acting on them. The coefficient of friction is noted, which will affect the contact forces. The conversation highlights the application of Newton's laws to solve for the contact forces between the crates.

Homework Statement



Three crates are arranged. Their masses are m1=29.8, m2= 15.3, m3= 27.3. The applied force of 910 N is directed horizontally and the coefficient of friction is u= .277

WHAT IS THE MAGNITUDE OF THE CONTACT FORCE BETWEEN M1 and M2?
WHAT IS THE MAGNITUDE OF THE CONTACT FORCE BETWEEN M2 and M3

Your answer for the acceleration of all 3 blocks looks correct. What's the acceleration of each block? Answer that question and then draw free body diagrams of the blocks and use Newton's laws for each block.
 
isn't the acceleration the same?

yes, they are.
 

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...
