    Ball Force Mass
AI Thread Summary
To calculate the mass of the suspended ball, the horizontal force (F = 9.5 N) and the angle (theta = 10°) are essential. A free body diagram indicates three forces acting on the ball: gravitational force (Fg), the applied force (F), and the tension in the string (Ft). The mass can be determined using the relationship between these forces, particularly focusing on the vertical and horizontal components. Once the mass is calculated, the tension in the string can also be derived from the equilibrium of forces. Assistance is requested for further clarification on the calculations involved.

Homework Statement


In the diagram above, the horizontal force, F, holds the ball steady. The value of the force is F = 9.5 N, and theta = 10°.


Calculate the mass of the ball.


What is the tension in the string?


Homework Equations


?


The Attempt at a Solution


I drew a free body diagram. The ball had 3 forces acting on it. Fg, F and Ft.
how do I find the mass? Then I'll be fine to find the tension.

Sorry
 
Could someone help me please?
 
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...
