The Amount of Time It Takes for an Object Bounce $T = 2 \pi \sqrt { \frac { m } { k } }$

question 22

Essay

The amount of time it takes for an object bounce up and down through one complete cycle is
called the "period" and is calculated using the following equation: $T = 2 \pi \sqrt { \frac { m } { k } }$
where
$\begin{array} { l } T = \text { period in seconds } \\m = \text { mass of object in kilograms } \\k = \text { spring rate }\end{array}$
What is the appropriate unit for $k$ if the preceding equation is to be homogeneous in units?
