1.	A cyclest is riding a bicycle on a circular track in a horizontal plane with maximum possible speed on the track. Coefficent of friction between the track and cycle tyre is mu on seeing a cat on the track, the cyclist applies brakes so hard that the tyres of the cycle stop rotating abruptly. Let veca_(1) and veca_(2) be the acceleration of bicycle just befor and just after the brakes applied, then \|bar(a_(2))-bara_(1)\| is
