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.

As the friction between the tyres and road reduces on a rainy day.

As F = rate change of momentum F = 1kg-m/s² = 1N
As F = rate change of momentum F = 1kg-m/s² = 1N
