(chatquestion)...23. On a large slippery ground, a boy left his dog sitting and walks away with a constant velocity v = 2.0 m/s. When he is xo = 199 m away from the dog, the dog decides to catch him and thereafter move together. The dog cannot develop acceleration more than a = 2.0 m/s? in any direction. In what minimum time will the dog meet the boy?
