Homework Statement



Describe the energy conversions of a device which is on a spring which is compressed then released and then spring bresks the device bounces up in the air.

Homework Equations



ignore air resistantance

The Attempt at a Solution



The device goes from strain energy to kinetic energy at the highest point it has potential energy then goes back down with kinetic energy then reaching the ground with ending of sound energy with the noise

What else can I say for 7 marks?

assume a compersion in spring and thus calculate max velocity of the device
find max height that device gains and its petential energy there (assume refrence as ground)
or even you can calculate the time period of the continuous motion

Thanks but the q did not ask for calculation

Just a description
