HELP - IBMath Vectors HW - Radio Transmitters
AI Thread Summary
The discussion revolves around seeking assistance with homework problems related to radio transmitters that require the use of vectors. The user has attempted some questions but primarily used the Pythagorean theorem instead of vector methods. They express confidence in solving parts A, B, and C but find parts D, E, and F challenging. The request for help emphasizes the need for vector-based solutions. Overall, the user is looking for guidance on how to approach these specific vector problems effectively.

yes, but i sort of used pythagerus to solve them, not vectors...
A, B, C i can do fine... but D, E, F bit sketchy...
So any help would be appreciated... Thanks!

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...
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
$$T + f_f - N_w = Ma$$

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.
