You can try this with a conker on a string. It is just motion in a circle with constant angular speed $\omega$. Remember that the acceleration towards the centre is $r\omega ^2$ where $r$ is the radius of the circle. Resolving horizontally use 'force = mass times accelaration'.
The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to embed rich mathematical tasks into everyday classroom practice.
