Problem
A hover-puck glides nearly friction-free across a gym floor. A high-speed camera captures its position every 0.04 s. A portion of the data is shown.
Time (s) | Position (m)
0.00 | 0.000
0.04 | 0.048
0.08 | 0.208
0.12 | 0.432
0.16 | 0.688
Using only the information provided, analyze the puck’s motion.
(a) Determine the average velocity of the puck during the interval from 0.08 s to 0.12 s. Show your calculations and include units.
(b) Determine the average velocity of the puck during the interval from 0.04 s to 0.08 s. Show your calculations and include units.
(c) Which of the two values calculated above provides the better estimate of the puck’s velocity at 0.08 s? State the value you choose and justify your selection based on the data.
