    Massless Tension
AI Thread Summary
The discussion focuses on calculating the tension in two massless cords supporting two 2.0 kg paint buckets. When at rest, the tension in each cord equals the weight of the buckets, which is 19.6 N. If the buckets are accelerated upward at 1.30 m/s², the tension in the upper cord increases due to the additional force required for acceleration. Participants suggest using free body diagrams to visualize forces and applying the equation F=ma for calculations. Understanding these principles is essential for solving the problem accurately.

Homework Statement


One 2.0kg paint bucket is hanging by a massless cord from another 2.0 kg bucket, also hanging by a massless cord.

a) If the buckets are at rest, what is the tension of each cord?
b) If the two buckets are pulled upward with an acceleration of 1.30m/s2 by the upper cord, calculate the tension in each cord.

Homework Equations


F=ma

To start, draw a picture of what is going on to help you organize your thoughts. F=ma would be a relevant equation.
 
Draw a free body diagram of each can separately.
 

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...
