On a cliff of length 110m at a height 240m, 10 cats are positioned facing either the left or right direction arbitrarily. The length of the cliff is large compared to the size of each cat. Initially, all cats start running
in the direction they are facing at a speed 12m/sec. Whenever any cat collides with another cat, both the cats instantly reverse their respective directions and continue running. When a cat reaches the ends of
the cliff, it falls down.on average, how much time does it take for all 10 cats to fall off the cliff?

Answer:
For every action there is equal and opposite reaction.
So for every initial (left, right) collision we have (right, left) outcome.
All cats are same!
For worst case if we assume they start from extreme points... maximum 110m distance is travelled at 12m/s speed by most of the cats(others will fall at start).
Hence 9 sec approx.
