Force Mass Mechanics Time

AI Thread Summary

The discussion revolves around a student's struggle to understand a physics problem related to force, distance, mass, and time. The student admits to feeling clueless despite having notes. Another participant emphasizes the importance of attempting the question to adhere to forum rules. They suggest considering the role of friction when analyzing the scenario of a box being pushed at a uniform velocity. Understanding these concepts is crucial for solving the problem effectively.

Homework Statement: A 15 kg box is pushed with a constant horizontal force of 85 N along a level surface. If the box moves with a uniform velocity of 6.0 ms–1, how much net force is required to accelerate it uniformly to 12 ms–1 in 2.0 s?

Relevant Equations: netforce = ma

...more equations I'm just so confused on which one to use (like SUVAT equations)

I'm sorry but I can't even attempt this question since I'm pretty much clueless, I got the notes but I don't understand them.

Yah, no attempt is not going to work here. (forum rules ) -- see:

Perhaps you should be looking into the friction that occurs while the box is being pushed with uniform velocity?

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:
