Calculate the acceleration of a biker travelling around a circular path of 36.9 meter radius at 19.9 m/s
The acceleration is into the centre of the motion and
a = v^2 /r
a = 19.9^2 / 36.9
a = 10.7 m/s 2
I think that's right but I am pretty new to this stuf too.

This you tube showed a proof - I thought it was interesting but if you don't follow it or don't want to know about it, it won't matter
you just need to remember the formula.
