Help with finding missing quantities on Free-Body Diagrams

AI Thread Summary
In the discussion, the user seeks help with calculating missing quantities on a Free-Body Diagram, specifically FNet, acceleration (a), and force (F1), given that velocity (V) is constant. The user notes that the body is not accelerating, implying that the net force (FNet) acting on it must be zero. The relevant equations indicate that FNet equals the sum of all forces acting on the object, which should balance out to maintain constant velocity. Despite reviewing class notes and the textbook, the user is uncertain about how to proceed with the calculations. Understanding that the forces must balance is key to solving for the missing quantities.

Homework Statement


Fill in the missing quantity for the following:

V = constant
FNet = ?
a = ?
F1 = ?

Homework Equations


FNet = Fn - Fg + Fa - FF
Fg = mg
FNet = ma

The Attempt at a Solution


Because I honestly do not know how to go about solving this, the only things I've done are review class notes and consult the textbook, both of which have left me empty-handed.

The diagram is rather crude, but I'll assume:
- all force lines are supposed to have arrows pointing away from the block
- all force lines are parallel
- the body is not accelerating
If the body is not accelerating, what do you know about the (vectorial) sum of the forces acting on it?
 

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...

Thread 'Collision of a bullet on a rod-string system: query'

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'

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...
