Homework Help Overview

The discussion revolves around the calculation of velocity in the context of a marble falling from a height and traveling horizontally. Participants are exploring the relationship between time, distance, and trajectory in this scenario.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are examining whether the time taken for the marble to fall vertically is the same as the time taken to travel horizontally. Questions are raised about the impact of trajectory on the time taken for these distances.

Discussion Status

The discussion is ongoing, with some participants seeking further clarification on the relationship between vertical and horizontal motion. There is an exploration of how trajectory might influence time, but no consensus has been reached.

Contextual Notes

Participants are working within the constraints of understanding basic kinematics, particularly the independence of vertical and horizontal motions. There is an emphasis on the need for detailed explanations regarding the assumptions made about time and trajectory.

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.

does the trjectory affect the time taken ?
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.
 
Thanks very much doc
