Which one of the following person is in an inertial frame of reference? (a) A person (man) in a train which is slowing down to stop. (b) A person (child) revolving in a merry-go-round. (c) A person (driver) in a bus which is moving with constant velocity. (d) A person (pilot) in an aeroplane which is taking off.

Answer: (c). An inertial frame is one that is not accelerating. A slowing train, a merry-go-round and a plane taking off are all accelerating. A bus moving with constant velocity has zero acceleration. So the answer is (c).
