Hi,(adsbygoogle = window.adsbygoogle || []).push({});

A child on a swing swings with a time period of 2.5s and an amplitude of 2m.

What is the max. kinetic energy of the oscillation?

I'm not sure how to work this out without her mass. Her max speed is 2.51m/s but I dunno how to do this. BTW this is all the information that is given

Any hints?
