AI Thread Summary
To find the size of the force acting on a 50 kg body being pulled with an acceleration of 2 m/s² on a horizontal plane at a 30-degree angle, the friction coefficient is 0.2. The user attempted to apply Newton's second law and break down the forces into components along the x and y axes. They are uncertain whether the "size of the force acting on the body" refers to the horizontal component (Fx) or the vertical component (Fy). Clarification on this terminology is sought, as understanding the resultant force is crucial for solving the problem effectively. The discussion emphasizes the need for clear definitions in physics problems.

Homework Statement


One body whit m=50kg is pulled whit a acceleration a=2m/s2 on an horizontal plane whit an unknow force F which is making whit the plane an angle of 30 degree
The friction coeficient betwen the body and plane is \mu=0.2.Find the size of the force F.

m=50kg
a=2m/s2
\mu=0.2
\alpha=30

Homework Equations


The Attempt at a Solution


Well i tried to calculate the force whit Newton's formula F=m*a;
Then whit force compontents on Ox,Oy
Oy:N-G-Fy=0
Ox:Ff-Fx=m*a

But my question is "size of force acting on the body" is Fx?!or Fy?!

Resultant.
 
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 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
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...
