AI Thread Summary
To calculate the work done while climbing stairs, use the formula for gravitational potential energy, which is W = mgh, where m is mass, g is the acceleration due to gravity (approximately 9.81 m/s²), and h is the height gained. Given the mass of 77 kg and a vertical height derived from the distance climbed, you can determine the work done against gravity. The time taken to climb the stairs is not directly needed for this calculation. This approach simplifies the process by focusing on potential energy rather than forces and angles. Understanding this concept allows for an accurate calculation of the work done while ascending stairs.

I am working on a lab and I'm not sure how to calculate the work (done by me).

I know work = W=(F Cos theta) and Force =F= W/t

In the lab I am to walk up a set of stairs and time myself. I did this and got the following:

t=8 sec
d=6m
Mass(me)= 77kg

how do I find W?

Any pointer is greatly appreciated. I know I'm making this harder than it has to be I'm sure.

I assume that by 'weight', you mean weight in the layman sense and actually mean mass, given that your units are in kilograms. (Wow, 374kg's quite a bit)

Anyway, the work done by you (against gravity) is simply the increase in (gravitational) potential energy of your body, without having to re-derive and consider forces and direction and whatnot (which may not be very intuitive in such a scenario of climbing stairs).
 

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...
