dX
The time of the marble’s flight through the air (tflight) is calculated from height of the table.
Solve for time (t) given initial vertical velocity (ViY) of zero and using acceleration (a) due to gravity and
measured height of table (dy) of ______ meters.
√
Time of flight is _______ seconds.
Horizontal velocity calculated using multiple photogate time (tmarble) measurements of the marble at the
edge of the table. The diameter of the marble was measured (dmarble = 0.012 m).
