Curve Fitting Data: Motion Analysis, Bouncing Ball, Excel Graph

AI Thread Summary
The discussion revolves around analyzing the motion of a bouncing ball using data tracked by motion analysis software. The user imported the position data into Excel and seeks guidance on the appropriate function to fit the data, questioning whether it involves a geometric series. They are utilizing the online tool ZunZun for curve fitting and are uncertain about which function to select. The user suspects the data may represent an infinite geometric series. Overall, the focus is on identifying the correct mathematical model for the bouncing ball's motion.

Homework Statement


This is not homework, just a personal project. I do not know if this is the correct section to post, sorry if it's not. I'm using a motion analysis software to track the position of a bouncing ball (y vs t). I imported the data into Excel and the graph is attached. What type of function is this? Does it involve the geometric series? I'm trying fit the data using http://zunzun.com/. Which function should I choose? Thank you.

I believe this would be an infinite geometric series.
 
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 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
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...
