    Car Mass
AI Thread Summary
The discussion revolves around calculating the mass of a rail car using the force exerted on it. A participant expresses confusion over the calculation, questioning why the force of 10,000N divided by 10 cars does not yield the expected mass of 1,000kg. They argue that the force acting on the 11th car is responsible for moving all 10 cars, not just one. There is also mention of an online practice exam where the answer key seems incorrect. The participant plans to address this discrepancy with their professor.

I'm confused. Why isn't it 10000N/10car=1000N*1m/s^2=1000kg

Isn't the force The force exerted on the 11th car is moving 10 cars, not just one.

this equation is very confusing

yes, who checked off 'c'?
 
It was a practice exam online with the answer key. I guess I will tell the professor
 

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...
