Acar drives at a constant speed of 3m/s around a circle with radius 20m. what is the centripetal acceleration of the car

Centripetal acceleration, a=0.45m/s²

Explanation:

Centripetal force is a force that causes a body( such as car) to move in a circular motion.

F= mv²/r

And its acceleration is called centripetal acceleration.

F=ma

ma= mv²/r

a= v²/r

Given that v=3m/s and r= 20m

a= 3²/20 =9/20

a= 0.45m/s².

Therefore the centripetal acceleration of the car is 0.45m/s²
