AI Thread Summary
To calculate the tension in each piece of rope in an accelerating balloon system, the net force equation F = ma is applied. The upward force (Fa) and the gravitational force (Fg) acting on the balloon must be considered, leading to the equation Fnet = Fa - Fg. For the bottom rope, the tension is derived from the difference between the upward force and the weight of the balloon. The user is seeking assistance with this problem, which is due soon, indicating urgency for a solution. Understanding the forces involved is crucial for accurately determining the tension in the ropes.

Homework Statement


If the balloon in the diagram drawn below is accelerating upwards at 0.40 m/s (squared), calculate the tension in each piece of rope. Assume that the rope has no mass.

The diagram:

Homework Equations


F = ma

The Attempt at a Solution


For the bottom piece of rope
Fnet = Fa - Fg
Fnet = ma - mg
Fnet = (9.00)(0.40) - (9.00)(9.8)

where Fnet is the tension in the piece of rope, Fa is the force accelerating the balloon upwards, and m is the mass of the object held up by the rope

no help?? I have this problem set due tomorrow.. any answer would be so appreciated
 

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 '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...
