vertical acceleration

2
Asperas, Marco Physics 11 Mr. Cartajenas Experiment September 5, 2006 Vetical Acceleration Problem: Vertical acceleration is a constant value. This investigation will use that concept to calculate the vertical height of the CIS building. Hypothesis: 6.096m (10ft/storey, 10ft ≈ 3.048m, 3.048 * 2 = 6.096) Materials: 1. Ball 2. Stopwatch Procedure: 1. Position one member at the top of the building and one at the bottom. The member on top holds the ball and the one at the bottom stands close to the landing site with the stopwatch. 2. Drop the ball and immediately start timing. 3. Obtain the time it takes for the ball to drop (in seconds). 4. Repeat the process four times and get the average time. 5. Using the formula y = y0 + ½ gt^2 (g = -9.8m^2), find the distance (y, in meters) of the building. Data: Trial Time (seconds)( ±0.06) 1 1.13 2 1.21 3 1.15 4 1.17
