table offset. A plumb bob remained at the end of the table to mark the point where the table offset began. With the Vernier computer interface already connected, my group then opened a specific Logger Pro file titled "08B Projectile Motion." Following, my group recorded the initial speed of a steel ball being launched from the Projectile Launcher 10 times (see handout for directions on how to load and shoot Launcher). During those 10 shots, the ball was shot into a cardboard box which was held by yours truly. We recorded those values in Table 1, and used those values to calculate the average, maximum, and minimum speed of the ball, as seen in Table 2. We recorded the height of the table from the floor to the table top and added the provided height of the Projectile Launcher to the value. Next, we used our measurements to predict how far the ball will launch in Table 3. We taped a white piece of paper onto the ground where the ball was predicted to land then taped a piece of carbon paper on top of it. We shot another ball, and if it hit the paper, we removed the paper and measured the distance from the mark it made to the plum bob, recording the measurements in Table 4.
