Elevator Acceleration and Ball Gets Dropped

AI Thread Summary
An elevator descends from a height of 100 meters with a uniform acceleration, and after 5 seconds, an object is dropped, hitting the ground 3 seconds later. To solve for the acceleration, the initial height of the elevator at the time of the drop must be determined. The problem requires applying kinematic equations to relate the elevator's motion and the object's free fall. Participants are encouraged to share their attempts to facilitate targeted assistance. The discussion aims to clarify the relationship between the elevator's acceleration and the height from which the object is dropped.

Homework Statement



An elevator accelerates from the top floor at 100 m height downward with a uniform acceleration of a. After 5.0 s, an object is dropped out of an opening in the door, and that
object hits the ground 3 s later. Find a. How high up was the elevator when the object was dropped?

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...
