AI Thread Summary
The discussion focuses on sketching velocity and acceleration graphs for a person's movement starting 50m north of a reference point, walking to 50m south, jogging back to 50m north, and finally running to the reference point. Participants suggest placing the north-south axis vertically and the time axis horizontally to visualize the position over time. The slope of the graph will vary, being steeper during running compared to walking due to increased speed. Understanding these slopes is crucial for accurately representing velocity and acceleration in the graphs. Visual aids are requested to enhance comprehension of the concepts.

A person starts 50m [N] of a reference point then walks until hs is 50m of the reference point. The person then jogs until he is 50m [N] of the ref. point. The person then runs until he is at the ref. point.

How do i sketch a velocity vs time graph and an acceleration vs time graph for this scenario.

Any help is appreciated. Visual images would be nice

Thanks!

Put the north-south axis on the vertical (where the y-axis usually is), and the time axis to the right. Now sketch the person's position as a function of time. For the part where the person is running, will the slope be greater or less than when they are walking?
 

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...
