Question

can someone help me with this prelab? and explain the answers you got? thank you in advance!

1. Draw a graph of the equation: y 4.9 m/s2 t2 with horizontal axis (t) spanning from O to 2 seconds and vertical axis (v) spanning from 0 to 5 meters. (Note: This is different from last week's pre-lab ir which you graphed y vs. t2, here we are asking for you to graph y vs. t). 2. In generating a best fit line to your physical data using a mathematical equation, your computer estimates the value of fit parameters that yield the optimal fit to your data. Your computer also estimates the precision of those fit parameters via an uncertainty value. In this lab you will produce best fit curves according to the equation y = A You may find a fit parameter to be something like A t A 4.92 0.02 [m/s]. To match the physical model, you also have A ig-4.92+0.02 [m/s']. You know how to solve for g here, but how do you propagate the uncertainty? Reference the section on Uncertainty Analysis in the manual for Lab 1, and use Eq. 5 from the Lab 1 manual to determineg &g for the given A. 8x (Eq. 5)
