Question

Question:
A race car starts from rest and travels along a straight road until it reaches a speed of 26 meters per second in 8 seconds. The v–t graph consists of three segments: v equals 3.5 times t, for t from 0 up to 4 seconds; v equals 14 meters per second, constant, for t from 4 seconds to 5 seconds; and v equals 4t minus 6, for t from 5 seconds to 8 seconds. Draw the a–t graph and determine the maximum acceleration of the car.

Problem 12-48: Engineering Mechanics- Dynamics (Hibbeler 14th Edition)

This lesson shows how to derive the acceleration–time graph from a piecewise-linear velocity–time graph by differentiating each linear segment. Students practice applying the definition a = dv/dt to obtain constant acceleration values on each interval and identify the maximum acceleration.

In this lesson, you will learn to:
• Apply the definition a = dv/dt to find acceleration from a piec
