Question

What is the speed of the marble just before it rolls off the table?The horizontal speed is constant. Use several observations to calculate the time interval accurately.

How long does it take for the marble to fall from the top of the table to the floor? Where along the x-axis does the marble hit the floor? Neglect any air resistance.
NOTE: Both answers must be correct to get credit.

At what angle does the marble hit the floor? Use +x-axis to be 0 degree going counter-clockwise.

What is the position of the marble 0.034 s after it rolls over the edge? Put the x coordinate in the first box below and the y-coordinate in the second box.

Explanation / Answer

In the other question, you commented that you had the first answer right, using 0.6 m for distance.
I assume you meant: using 0.6 m/s for velocity.

If that is the case, I'll continue using that value.

(you also commented that 'time to hit the floor' and 'position when hitting the floor' were correct, so I'll just do 'the angle when hitting the floor' and 'position at time t=0.034 s)

The vertical velocity will also be correct the way I did it in the other question.
