Answer 1

when a person sitting on the front seat projects a ball vertically upwards , after some time the ball will falls on the back seat of the jeep .

reason :- Both during its upward and downward motion, the ball continues to move
inertia of motion with the same horizontal velocity as the train. In this period, the ball covers the same horizontal distance as the train and so it comes back to the thrower’s hand.
