AI Thread Summary
The discussion centers on the reaction times of the foot and hand, with an initial belief that the hand reacts faster due to its proximity to the brain. Participants seek clarification on how Newton's laws can explain this difference in reaction time. There is also a question regarding measurement accuracy, noting that the foot's distance to the ball was measured in centimeters while the ruler's measurement was in millimeters, suggesting visibility issues during measurement. Lastly, the conversation touches on the classification of both rockets and rulers as projectiles, despite their differing trajectories, indicating a need for more context to fully understand the underlying physics. Overall, the thread emphasizes the importance of clear problem statements in discussing physics concepts.

Hi ! I have many questions and I did try to answers them, but I want to know if I am incorrect.
1) Which reacted faster, foot or hand ? try to use Newton explanation
I think the hand will react faster because it is closer to the brain... to send signal, but I am not sure how to explain that with Newton laws ( 1st and 2nd )

2) Why was the distance betweeen the top of the foot and the ball only measured to the nearest centimeter, while the place that caught the ruler was measure to nearest millimeter?
My guess is that with the ruler I could see the measurement and when the ball drop on the foot, the measurement is off by some millimeter.

3) Explain why the rocket and the ruler are both projectiles, despite their different paths.
this question I HAVE No idea.

Hi lostsummer, welcome to PF. It would help us help you if you posted the statement of the problem with the underlying physical situation, instead of just the questions related to it. We are not mind readers, you know.
 

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...
