    Yes, the time 't' is the time the marble takes to fall the distance H2, which is also the time it takes to travel the distance 'd'. So it's the same time for both.

    thanks doc ,can you explain in detail, how the time will be same for both the distance?

    does the trjectory affect the time taken ?

    I'm not sure what you need explained. Going from b to the floor takes a certain about of time. So, in that same time the marble travels a vertical distance and a horizontal distance.

    The marble is traveling horizontally when it leaves the table. So the vertical speed is 0. That's all you need to find the time, regardless of the horizontal velocity.
