QUESTION $7$: In the grid below, create a graph of $T^2$ vs$.m$ with the $m$ on the horizontal axis and the squared period $T^2$ on the vertical axis. Don't forget to include the labels $($with units$)$ on both axes!

Draw a straight line through your data points and the origin using a transparent ruler.

Graph $2$: Period $($squared$)$ us$.$ mass

QUESTION $9$: Use the slope of Graph $2$ to estimate the spring constant $k$ of the spring.

Slope of best$-$fit line in Graph $2$: $$

Spring constant $k$ derived from Graph $2$: $q,$

$q,$
