Hw 3 part 1

Hello,

I am struggling to plot Plot the polyfit lines for velocity and position . Here is my data

[cooperrc]

np.polyfit returns polynomial coefficients, so

>>> np.polyfit(t, x, 1)
[37.7, 1.8]

is telling you the best-fit line is

$x(t) = 37.7 t + 1.8~m$

where

$x(t) = v_0 t + x_0$
