Explain me this concept (Laws of Motion)

AI Thread Summary
The discussion focuses on analyzing the motion of two blocks stacked on a smooth surface when a horizontal force is applied to the lower block. To derive the equations governing their motion, Newton's second law (F = ma) must be applied separately to each block. The frictional force between the blocks, characterized by the coefficient of friction (μ), plays a crucial role in determining their acceleration and interaction. Participants are encouraged to share their derived equations and insights to clarify the problem. Understanding these concepts is essential for grasping the laws of motion in this context.

Two blocks placed one on top of the other are lying on a horizontal smooth surface. The coefficient of friction between the blocks is \mu.

Case 1: Horizontal force F is applied to the lower block (Fig. 14).

Please help me to find out how they have got those equations. I'm trying to find it from past several hours but couldn't got any hint.​

Hi snshusat161! :smile:

(your link isn't working … it's http://www.monbattle.com/1.jpg" :wink:)

You need to do good ol' Newton's second law (F = ma) twice, once for each block.

What equations do you get? :smile:​

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...
