AI Thread Summary

To pull a block weighing 5N with a rope that can withstand 20N, the minimum force exerted must be greater than 5N but less than or equal to 20N to avoid breaking the rope. A free-body diagram illustrates the forces acting on the block, including tension and gravitational force. Applying Newton's second law, the net force must equal the mass times acceleration. Therefore, the force required is calculated by ensuring it does not exceed the rope's limit while overcoming the block's weight. The solution confirms that a force of 5N is necessary to start moving the block without breaking the rope.

If we want to pull a block with a weight of 5N attached to a rope that is just able to resist 20N. What is the minimum force that we need to exert in order to not break the rope? xD

Draw a free-body diagram on the block, write out Newton's second law, and solve!

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
