Problem 1. (22-10-2013)
********************
The luckless cat is thrown into a circular arena of radius R containing a Dog. Initially the dog is at the centre O of the arena while cat is at the perimeter. Cats strategy is to run with his maximum speed u around the perimeter. The dog responds by chasing at his maximum speed u in such a way that it remains on the position vector of cat with centre of circle as origin. Find after travelling what distance and what time will the dog catch the cat
