Apparatus: Tray held on by two sheets of metal of approximate dimension (each: 1"x10"x1/16"), that was clamped onto the edge of the lab table.There was a tape on the tray side,which was suspended in the air, that was used as a marker of position every time the tray would oscillate through a photogate. The photogate measured the period of the swinging tray. 0-800 g of mass were added to the tray in 100g increments, and period was measured each time.
Theory: T= A(mass+Mtray)^n
Using the data we inputted into the computer, we determined that the mass of the tray was between 320g and 420g.
Unknown 1 had a period of .3908s with a measured mass of 174 grams
Unknown 2 had a period of .3344s with a measured mass of 78 grams.
Lab Partners were Kyle and Cesar.
