please help me plot the graph for these two trials, it should be the best fit line and also help me find the slope thank you
Physics Laboratory Experiment - Straight Line Motion At
Purpose:
In this experiment, the position of a bulldozer moving in a straight line is measured at
various times, to determine the bulldozer's speed.
Procedure:
1. Allow a toy bulldozer ton travel across
table top or the floor for a distance of 3 or 4
meter in a test run,
2. Place a tape measure or a series of meter sticks along the path of travel. Start the
bulldozer a few centimeters before the starting line. When the bulldozer reaches the
starting line, start keeping track of the timne with a stop watch or sweep second hand.
3. Five seconds after the bulldozer crosses the starting line, record its position. Without
stopping the bulldozer, repeat this procedure at 5-second intervals. Enter all of the data in
the first column of the data chart,
4. Reduce the speed of the bulldozers by forcing it to drag a load behind as it traveſs.
Following the procedure above, record the position of the bulldozer at the end of each 5
second interval in the second column of the data chart.
5. Add heavier weights behind the bulldozer to reduce its speed further and record
position and time in the remaining columns of the data chart.
