Estimating Car Velocity over 10 Seconds

Click For Summary
SUMMARY

The discussion focuses on estimating the velocity of a car over a 10-second interval using 5 subintervals and midpoints. Participants debated the selection of midpoints, ultimately agreeing on using the times (1, 3, 5, 7, 9) for calculations, as the endpoint at 10 seconds does not serve as a midpoint. The suggested approach emphasizes the importance of midpoints in numerical estimation methods. Additionally, visualizing the data points is recommended to understand the impact of different midpoint selections.

PREREQUISITES
  • Understanding of basic calculus concepts, specifically Riemann sums.
  • Familiarity with velocity-time graphs and their interpretation.
  • Knowledge of numerical estimation techniques.
  • Ability to plot data points for visual analysis.
NEXT STEPS
  • Learn about Riemann sums and their applications in estimating areas under curves.
  • Explore the concept of numerical integration techniques, such as the Trapezoidal Rule.
  • Study the impact of different midpoint selections on numerical estimates.
  • Practice plotting velocity-time graphs to visualize motion over time.
USEFUL FOR

Students in physics or calculus courses, educators teaching numerical methods, and anyone interested in understanding motion analysis and numerical estimation techniques.

i just don't know which times i should take the midpoints. I am debating between taking times at (1,3,5,7,9) and (2,3,6,8,10). can sumone help me?
 
I would take the midpoints at (1,3,5,7,9). Just because 10 isn't a midpoint. You don't know the value at 11.
 
It shouldn't really matter ... but midpoints are always the best.

For understanding plot these points and see what happens
if pick left points, middle points, or right points
 
alright thanks guys =)
