Circular Motion example 2

The video tutorial explains how to calculate the acceleration vector of a car on a circular racetrack. Starting from rest, the car reaches a speed of 200 km/h at the finish line. The tutorial covers defining variables, setting initial conditions, and deriving both tangential and normal acceleration components. It concludes with expressing the acceleration vector in Cartesian coordinates.

What is the significance of the radius of the circular track in determining the car's acceleration?

How does the car's speed change as it travels around the circular track?

How can the acceleration vector be expressed in Cartesian coordinates?
