In the figure the top view of a compartment of a train is shown. A man is sitting at a corner 'B' of the compartment . The man throws a ball ( with respect to himself ) along the surface of the floor towards the corner 'D' of the compartment of the train. The ball hits the corner 'A' of the compartment, then find the time at which it hits A after the ball is thrown . Assume no other collision during motion and floor is smooth. The length of the compartment is given 'l' and the train is moving with constant acceleration 'a' in the direction shown in the figure.
