3. 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.

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 b) (10 pts). Find the % difference between the instructor's calculated value and your calculated value of velocity. Show your work (including the units). (Use the instructor's value as the standard) % diff =
