Question

Question:
The velocity-time graph for a car moving along a straight road is defined as follows: velocity equals 0.6 t squared, for t between 0 and 5 seconds; and a straight line dropping from v equals 15 meters per second at t equals 5 seconds, down to v equals 0 at t equals 15 seconds. At time t equals 0, the position s equals 0. Part one: determine s as a function of t and a as a function of t for each interval. Part two: find the average speed and total distance traveled over the full 15-second interval.

Problem 12-54: Engineering Mechanics- Dynamics (Hibbeler 14th Edition)

This lesson derives position and acceleration functions from a piecewise velocity–time graph for a car moving along a straight road. Students integrate and differentiate the velocity functions over two intervals, then compute total distance traveled and average speed over a 15-second window.
