Stationary elevator homework problem

AI Thread Summary
To solve the stationary elevator problem, consider Allison's apparent weight when accelerating upwards at 8 m/s². The scale measures the upward force on her, which can be calculated using Newton's 2nd law. By adding the acceleration to the standard gravitational force of 9.8 m/s², the effective gravitational force becomes 17.8 m/s². Consequently, Allison's apparent weight is her mass multiplied by this new gravitational force. Understanding these concepts clarifies how acceleration affects perceived weight in a stationary elevator scenario.

I'm doing this Physics worksheet and I don't know how to do this problem...
Allison is standing on a scale that is in a stationary elevator. what is the apparent weight when she is moving up at 8 m/s squared?

If anyone can help that would be great.. And if you could explain the steps you used to get it.

Thanks

The scale reads the force that pushes up on the girl. Draw a diagram showing the forces on the girl (there are two). The net force on the girl is related to her acceleration by Newton's 2nd law. (Hint: you can express the girl's apparent weight in terms of her actual weight.)
 
Just think of the acceleration upwards as more gravity.

The "gravity" has increased from 9.8 to 17.8 m/s^2.

Therefore her apparent weight is just her mass times the new "gravity".
 
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...
