Find the stiffness of the spring in a child's pogo stick if the child has a mass of 35kg and bounces once every 2.0 seconds.
T = 2.0 seconds m = 35kg
T = 2π√(m/k)
The Attempt at a Solution
Using the above, I figured k = mπ2 which worked out to be 345.44
This problem didn't have an answer in the back of the book. I saw a similar equation for frequency so I used the frequency/period relationship to formulate the above equation. I figured I should ask for a check in case I assumed wrong.
