CPM Homework Help : PC Problem 9-113

Sketch velocity and position graphs for the following scenario. Walk for 4 seconds, gradually increasing your speed. Stop for $1$ second. Walk slowly back towards start for $5$ seconds. Stop for $10$ seconds. Run towards the finish for $10$ seconds.

Velocity Graph:

First quadrant piecewise, pieces as follows: from origin to (4, comma 4), from (4, comma 0) to (5, comma 0), from (10, comma 0) to (20, comma 0), from (20, comma 6) continuing to the right.

Position Graph:

First quadrant continuous piecewise, pieces as follows: concave up curve from origin to (4, comma 4), horizontal to (5, comma 4), linear to (10, comma 2), horizontal to (20, comma 2), increasing to (25, comma 8).
