Question

The lab partners were investigating the velocity of a wheeled object recoiling down a track when a compressed plunger spring is released, and they recorded their data in the table below. However, the lab instructor told them that they had made a mistake somewhere, because their calculated results did not agree with the results of the instructor's own trial. Based upon the collected data shown above: Calculate the average velocity of the object for both the student and instructor trials. Use the formula of v=d/t and show your work (including the units). Velocity (Student) = m/s Velocity (Instructor) = m/s

Explanation / Answer

average velocity=total distance/total time=1.66/8=0.2075 m/s for instructor: average velocity=1.72/8=0.215 m/s
