An object is thrown upward by a person on a train that moves with constant velocity.

a) Describe the path of the object as seen by the person throwing it b) Describe the path of the object as seen by a stationary observer outside the train?

no

a) The person on the train sees the object move in a vertical path. The object initially moves upward, slows down, and eventually comes to a stop at its highest point. Then, it starts moving downward, accelerating due to gravity until it returns to the person's hand.

b) A stationary observer outside the train (not moving with the train) sees the object follow a curved path rather than a straight vertical path. This is due to the fact that while the object is moving vertically upward, the train is also moving horizontally. From the observer's perspective, the object appears to have an initial velocity in the horizontal direction, resulting in it moving in a curved path. The shape of the curve depends on the initial velocity of the object and the duration of its flight.
