    Angle Mass
AI Thread Summary
To find the angle of a 5kg mass suspended from a cord with a horizontal 23N force, it's essential to analyze the forces acting on the mass. The net force equation, Fnet=ƩFi=0, indicates that the system is in equilibrium. Using the weight of the mass and the applied force, one can resolve the forces into components to determine the angle. Drawing a diagram can help visualize the forces and simplify the calculations. Understanding these concepts is crucial for solving similar physics problems effectively.

A 5kg mass is suspended from a cord. The mass is held as shown with a horizontal 23N force. Find the angle

Homework Equations


Fnet=ƩFi=0

The Attempt at a Solution


I am not sure about the right way to find the angle but the variables given are force and the mass should I use the weight to find the angle? Is this a obtuse triangle?

The only thing my professor told me when I had difficulty with these types of problems was to use components. I would recommend drawing a picture or diagram with all the forces acting on the mass, that should make it easier to 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...
