AI Thread Summary
To find the distance the flowerpot falls from the windowsill to the top of the window, the time taken to pass the window (0.420 seconds) and the height of the window (1.90 meters) are used in the calculations. Ignoring air resistance, the distance fallen can be derived from the equations of motion. The initial solution provided indicates that the distance from the windowsill to the top of the window is approximately 0.31 meters. This calculation confirms the relationship between time, height, and free fall in physics.

A freefall problem

A flowerpot falls off a windowsill and falls past the window below. You may ignore air resistance. It takes the pot .420 s to pass this window, which is 1.90 m high. How far is the top of the window below the windowsill from which the flowerpot fell?

That looks good.
 
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...
