Relative motion with circular path and normal acceleration

Cars A and B are traveling around the circular race track. t the instant shown, A has a speed of 90 ft/s and is increasing its speed at a rate of 15 ft/s^2, whereas B has a speed of 105 ft/s and is decreasing its speed at 25 ft/s^2. Determine the relative velocity and relative acceleration of car A with respect to car B at this instant. Problem 12.225 Hibbeler Dynamics 15th 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
Intermediate Dynamics
Orbital Mechanics
Vector Basics

Thank you so much! my prof is terrible at teaching dynamics
