Question

Question:
The velocity of a car is plotted as a v–t graph. From t equals 0 to t equals 40 seconds, the velocity is constant at v equals 10 meters per second. From t equals 40 seconds to t equals 80 seconds, the velocity decreases linearly from 10 meters per second to 0 meters per second. Determine the total distance the car travels until it stops at t equals 80 seconds, and construct the a–t graph.

Problem 12-42: Engineering Mechanics- Dynamics (Hibbeler 14th Edition)

This lesson uses a piecewise linear velocity–time graph to determine acceleration and total distance traveled. Students learn to compute acceleration as the slope of the v–t curve and distance as the area beneath it, then construct the corresponding a–t graph.

In this lesson, you will learn to:
• Interpret a piecewise linear v–t graph to identify phases of constant velocity and constant acceleration
• Calculate accelerat
