1. Compute sin 9 and 6. Record the thickness of the block and uncertainty: Record the distance from the pivot to the block and uncertainty. Use these numbers to get sinB . Write the equation in letters, write the numbers in the equation. Write the answer. Fromsinnde. 2. Hold the cart near the top of the inclined plane, at least 10 cm from the motion sensor. 3. Start taking data. We are plating velocity versus time. The slope should be your acceleration. 4. Let the cart go down to the bottom of the plane. 5. Stop taking data. Use the line fitting tool to t the slope. 6. Record the slope and the uncertainty of the slope. Initial reduction: Make a copy or sketch of the graph to put in the lab report
