What Is the Constant Acceleration of the Departing Train?

AI Thread Summary
To determine the constant acceleration of a departing train, the problem involves calculating the time it takes for each car to pass a stationary observer. The first car, measuring 8.60 meters, passes in 1.50 seconds, while the second car passes in 1.10 seconds. The difference in time indicates a change in velocity, which is essential for calculating acceleration. By applying the definition of acceleration as the change in velocity over time, the solution can be derived. Understanding these principles is crucial for solving the problem accurately.

Homework Statement


Liz rushes down onto a subway platform to find her train already departing. She stops and watches the cars go by. Each car is 8.60m long. The first moves past her in 1.50 s and the second in 1.10 s. Find the constant acceleration of the train.

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...
