Problem $3$: $(7\%$ of Assignment Value$)$

Some undergaraduate physics students are studying periodic motion using an oscillating mass on a spring. After acquiring data, they plotted the position versus time graph shown.

The function that represents the data on the graph may be written as

$x=$Acos$(t+),$ with $,in[0,2)$

If the mass is $2\mathrm{.}82$ kg $,$ then what is the spring constant, in newtons per meter?

$k=|\frac{N}{m}||$
