Place the ball at the top of the ramp. Start the stopwatch when the ball leaves the bottom of the ramp. Stop the stopwatch when the ball crosses the 2 m mark. Record the time.| 2. Repeat Step 1 three more times. Be sure to release the ball from the same location on the ramp each time. 3. Repeat Steps 1-2, but measure the time it takes the ball to cross the 1.5 m mark. 4. Repeat Steps 1-2, but measure the time it takes the ball to cross the 1.0 m mark. 5. Repeat Steps 1-2, but measure the time it takes the ball to cross the 0.5 m mark. 6. Average the times for each distance and write them in the corresponding part of your data table. 7. For each distance, calculate the average velocity and write it in the corresponding part of your data table. 8. Graph the distance vs. time. Draw a straight line that represents your best guess about what the data represent and calculate the slope of the line [slope = (yz - y,) / (*2 - X,)] using two points that are not data points. Write the slope on your graph. (Note: Because the ball is always rolling in the same direction, which we consider positive, distance and displacement will be the same thing.) 9. Graph the velocity vs. time. Draw a straight line that represents your best guess about what the data represent and calculate the slope of the line | slope = (V2 - y,) / (*2 - X,)_ using two points that are not data points. Write the slope on your graph. (Note: Because the ball is always rolling in the same direction, which we consider positive, velocity and speed will be the same thing.)
