Question

Question:
A particle's position-time graph has been experimentally determined. From the data, construct the velocity-time and acceleration-time graphs for the motion over the interval 0 to 40 seconds. For 0 to 30 seconds, the position follows the equation s equals 0.4 t squared meters. For t greater than or equal to 30 seconds, the position-time graph becomes a straight line.

Constructing v–t and a–t Graphs from a Given s–t Graph

This lesson demonstrates how to derive velocity–time and acceleration–time graphs from a piecewise position–time function using differentiation. The position function consists of a parabolic segment followed by a linear segment, requiring analysis of each region separately. Students apply the power rule and continuity conditions to fully characterize the motion.


In this lesson, you will learn to:
• Differentiate a piecewise position function to obtain veloci
