12 .129 Hibbeler Dynamics curvilinear motion with normal and tangential coordinates

The car starts from rest at s=0 and increases its speed at a_t = 4 m/s^2. Determine the time when the magnitude of acceleration becomes 20 m/s^2. At what position s does this occur? Problem 12-129 Hibbeler Dynamics (14th edition)

Who am I?
I'm Cherish! I currently teach Mechanical Engineering at a University but I remember the days of being a struggling engineering student. Going to class, feeling confused and frustrated when trying to do assignments because I hadn't learned much in class seemed to be a regular occurrence.
I created STEM Course Prep to save today's engineering students from the same fate. I teach my courses in a way I would have liked to be taught... light on theory, heavy on examples.
Organization is key to learning so I also provide an outline of notes for my courses so you can stay organized and create a great resource for each course.
Current offerings:
Statics
Dynamics
Mechanics of Materials I and II
System Dynamics and Controls
Thermodynamics
Fluid Mechanics
MATLAB
Numerical Analysis
