Magnitude of total force of stone on a hand

AI Thread Summary
To determine the magnitude of the total force of the stone on the man's hand, the equation F = ma is applied, where F represents the total force, m is the mass of the stone, and a is the acceleration. The stone has a mass of 1.9 kg and is being accelerated upward at 1.5 m/s². The forces acting on the stone include the gravitational force and the applied force from the man's hand. The correct approach involves calculating the net force required for the upward acceleration and considering the weight of the stone. Understanding these forces is crucial for solving the problem accurately.

In the equation F = ma, what does F stand for? What forces act on the stone?
 
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...
