Math Problem Statement
Solution
The table provided contains time intervals and the corresponding velocities of a car in feet per second (ft/s). To find the total distance traveled along the twisty road, we need to calculate the approximate area under the velocity-time graph, using methods like the trapezoidal rule or rectangular approximations.
Would you like me to:
- Use the trapezoidal rule for better accuracy?
- Approximate using midpoint or left/right Riemann sums?
Let me know your preference! Here's how we could proceed: numpy as np
Time (s) and Velocity (ft/s) data from the table
time = np.array([0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120]) velocity = np.array([0, 18, 47, 35, 39, 28, 30, 47, 30, 19, 39, 36, 33])
Trapezoidal Rule to calculate the distance traveled
distance = np.trapz(velocity, time) distanceUsing the trapezoidal rule, the total distance traveled along the twisty road is approximately 3845 feet.
Would you like a detailed breakdown of the calculations or clarification on the method? Here are some follow-up questions to extend the discussion:
- Would you like to see the result using a different numerical approximation (e.g., midpoint or left/right Riemann sums)?
- Should we explore how the trapezoidal rule works step by step?
- Do you want to calculate the average velocity during this trip?
- Would you like to discuss how changing time intervals might affect the accuracy of the calculation?
- Should we convert the velocity into other units, such as miles per hour?
Tip: The trapezoidal rule is especially accurate for smoothly varying data but less so for irregular data points.
