Net Force Questions: Calculating Frictional Force

AI Thread Summary
To calculate the frictional force when an object is dragged at constant velocity with an applied force of 12 Newtons, the frictional force must equal the applied force, resulting in a frictional force of 12 Newtons. For the second scenario, a horizontal force of 15 Newtons acting on a 5 kg block producing an acceleration of 2 m/s² requires the use of Newton's second law to determine the net force, which is 10 Newtons. The frictional force can then be calculated by subtracting the net force from the applied force, resulting in a frictional force of 5 Newtons. Participants emphasize the importance of showing work, such as free body diagrams (FBD), to facilitate assistance. Clear calculations and diagrams are essential for solving these physics problems effectively.

Homework Statement


A student drags an object across a laboratory table at constant velocity using an applied force of 12 Newtons. Calculate the frictional force

2. a horizontal force of 15 Newtons pulls a 5 kg block along a horizontal surface. If the force produces an acceleration of 2 m/s(squared), what is the frictional force acting on the block?

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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

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...
