How Much Work Does a Machine Perform Between 9s and 18s?

AI Thread Summary
To find the work done by a machine between 9.0 seconds and 18 seconds, the power function is given as P = ct^2, with c equal to 18 W/s^2. The relationship between power, work, and time is expressed as P = w/t. To calculate the total work done, integration of the power function with respect to time is necessary, since P represents the rate of work done. The integration will provide the total work performed by the machine in the specified time interval.

Integrate with respect to time because:

P=\frac{dW}{dt}.
 
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...
