Quick Question on Conservation of Energy

AI Thread Summary
The discussion focuses on verifying calculations related to the conservation of energy, specifically involving work and velocity. The user calculated work as 0.5758 J and velocity as 0.7588 m/s, which were confirmed as correct by another participant. There is a suggestion to post additional questions (#3 and #7) in separate threads for better visibility and to include attempts at solutions. The user expresses frustration over a lack of responses for their previous attempts to get help. Clear communication and structured posting are emphasized for effective assistance.

Quick Question on Conservation of Energy! :(

#1.
Number1.png


For this one, I did

a) W = ½kx² = ½*410*.053² = 0.5758 J
b) V = √[2W/m] = √[2*.5758/2.00] = 0.7588 m/s

Are those right?
If so, can you help me solve Number 3 and 7 real quick!

Those answers look good.

I suggest posting #3 & #7 each in its own thread.

You will also be expected to post an attempt at a solution for each.

Did you post #3 ?
 

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'

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...
