The world record for pogo jumping is 122000 times in 15 h 26 min. What type of vibration is occurring in the spring of the pogo stick? Calculate the average period of vibration. Calculate the average frequency of vibration.

Question

anonymous · Answer

We can model the vibration as a sine wave. 
The average period of vibration is simply:$$t = {\rm time \over jumps}$$The frequency is: $$f = {1 \over t} = {\rm jumps \over time}$$
