How Is Tension Calculated in a Massless String System?

AI Thread Summary
In a massless string system involving two masses, m1 (5.8 kg) and m2 (5.2 kg), connected by a string and subjected to a pulling force of 30 N, the calculation of tension is complicated by the absence of acceleration data. The work done by the normal force on both masses is questioned, with the user expressing frustration over the inability to determine tension without knowing acceleration. The equation Δk = Wnet is referenced, indicating a focus on kinetic energy changes. Clarification is sought regarding any additional parts of the problem that may provide necessary context. Understanding the relationship between tension, force, and acceleration is crucial for solving this problem effectively.

Homework Statement


A mass m1 = 5.8 kg rests on a frictionless table and connected by a massless string to another mass m2 = 5.2 kg. A force of magnitude F = 30 N pulls m1 to the left a distance d = 0.87 m.
2)How much work is done by the normal force on m1 and m2?

Homework Equations



Δk=Wnet

The Attempt at a Solution



I was solving for V final when I realized that tension does work. How can you find the force of tension for this problem without the acceleration? I keep running in circles. Textbooks, etc. don't alleviate the headache. Help!

Is there a part 1 you are solving , but haven't told us about?
 

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...
