AI Thread Summary
To determine the speed of the new steamship, a scientist proposes measuring the time taken for the steamship to travel from point A to point B and back, denoted as t1 and t2, respectively. The distance between points A and B is represented as S, and the angle between line AB and the steamship's direction is noted as alpha. The discussion invites participants to provide solutions, emphasizing the importance of showing work for clarity. The goal is to calculate the steamship's speed based on the provided parameters. Engaging in this problem-solving approach can foster collaborative learning and understanding of the underlying physics concepts.

in order to find out the speed of a new steamship,a scientist comes up with a idea to slove it:He makes the steamship sail from A to B and then return to A from B(look at the image). only when the angle between the line AB and the direction of the sreamship is a,the streamship can sail though the line AB,and the time it takes is t1. and the time of coming back though BA is t2. the distance of AB is S. question:what is the speed of the new streamship?

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...
