    (A) : If bomb is dropped from an aeroplane moving horizontally with constant velocity then the bomb appears to move along a vertical straight line for the pilot of the plane. ( R) : If a bomb is dropped from an aeroplane moving horizontally with constant velocity then horizontal component of velocity of the bomb remains constant and same as the velocity of the plane during the motion under gravity.
