AI Thread Summary
To solve the elevator problem, the weight of the elevator is 1400 kg, and it initially moves downward at 12 m/s before coming to a stop over a distance of 41 m. The acceleration calculated is 1.75 m/s², which is used to determine the tension in the cable. The formula T = m(a + g) is applied, resulting in a tension of 16,170 N. This calculation effectively incorporates both the acceleration and gravitational force acting on the elevator.

Homework Statement


Elevator weighs 1400 kg with an initial velocity of 12 m/s (moving downward). With a constant acceleration, the elevator comes to a stop in 41 m. What is the tension on the elevator cable?


Homework Equations



T=m(a+g)

The Attempt at a Solution



I'm having trouble finding the acceleration of the elevator.

I got it, a=1.75 m/s\hat{2}

by v\hat{2}=v\check{i}\hat{2}+2a(\Deltax)

T=16170 N
 
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...
