Ok I got couple of home labs to do...but in few of them i m stuk at the end. Plz answer any question that you know of.(adsbygoogle = window.adsbygoogle || []).push({});

1. In this home lab, I did an experiment about strech (of a rubber band) vs weight (of coins attached to it). Then plotted a graph and found slope and y int as the question requested. However, the question ends like this...

...find the slope and y intercept. These values can be used to represent the uncertainities (delta)m, and (delta)b in y = mx + b. By comparing the best fit leanear equation (which is y = mx + b) to the predictions of Hooke's law, find

k +/1 (delta)k

- Now, it somewat seems easy to me, but no matter how many times i use the table (that i used for graphing) I just couldn't find the solution. Even after using equations such as F = kx or KE = 1/2mx(square). Any help is appriciated.
