AI Thread Summary
To find the direction of a 700 N force that results in a net force pointing due west when a 400 N force points Northwest, the required direction is South 66 degrees West (S66°W). The magnitude of the net force, when calculated, is 923 N. A vector diagram can aid in visualizing the forces involved. The discussion suggests using the sine rule for solving the problem. Understanding these concepts is essential for mastering kinematics and Newton's laws in physics.

Draw a vector diagram, then use relevant information from the question to help you with the values.

you might find a/sin(a) = b/sin(b) useful here if you have learned this identity before.
 

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...
