AI Thread Summary
To plot an acceleration-time graph from a velocity-time graph, one must determine the slope of the velocity graph, which represents acceleration. The provided velocity-time graph indicates a constant acceleration of -9.4 m/s². The user attempted to create an acceleration-time graph based on this information. Feedback suggests that the acceleration appears to be correctly represented as constant. Understanding that the slope of the position vs. time graph indicates velocity, while the slope of the velocity vs. time graph indicates acceleration, is crucial for accurate plotting.

Homework Statement


I need help plotting the acceleration time graph from a given velocity-time graph.

Homework Equations


I know you need to do slope [Which is already provided] [9.40 m/s2]

I also attached the distance-time graph [first one] and I also attached the velocity time graph [graph 2]

The slope of the position vs. time graph is velocity.

The slope of the velocity vs. time graph is acceleration.

Your acceleration looks reasonably constant at ‒9.4 m/s2.
 

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...
