What is the initial speed of a juming flea?

AI Thread Summary
To determine the initial speed of a flea that jumps to a height of 0.520 meters, users are encouraged to show their calculations or attempts before receiving assistance. The discussion emphasizes the importance of posting in the appropriate homework forum for such queries. Participants engage in light banter, but the focus remains on the need for a clear problem-solving approach. The conversation highlights the collaborative nature of the forum while maintaining academic integrity. Overall, the initial speed can be calculated using physics principles related to gravitational potential energy and motion.

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...
