A car initially traveling eastward turns north by traveling in a circular path at uniform speed. The length of the arc ABC is s metres, and the car completes the turn in t seconds.(adsbygoogle = window.adsbygoogle || []).push({});

What is the acceleration when the car is at B located at an angle of r degrees? Express your answer in terms of the unit vectors x and y component?

Determine its average acceleration during the t seconds interval.

Any hints to do this? What is the difference in ans between the 2? is there a need for calculus?
