Question

A fly travelling horizontally at a constant speed
enters the open window of a train and leaves
through the window on the opposite side 0.75 s
later. If the fly travels perpendicular to the train's
motion as seen from an observer on the ground,
and the train is travelling at 3 m/s and width of
train is 3m, determine the speed of the fly as
observed by a passenger on the train
(1) v = 1.000 m/s (2) v = 7.00 m/s
(3) v = 5,00 m/s (4) v = 2.65 m/s
