A rail-road car is moving towards right with acceleration a. A man A accelerating toward left with an acceleration of magnitude a/3 w.r.t. to car. A dog of mass m is following man A with an acceleration a/3 relative to the car. Observing the dog and man A. Find the a. net force experienced by the dog as seen by observer B standing on ground. b. rate of change of linear momentum of the dog relative to the man A moving on trolley. c. pseudo-force on the dog as seen from man A.
