Centripetal Acceleration

Question

Tamir drives his car around a circular section of a road having a radius of 20 meters at a constant

speed of 10 m/s. What is the centripetal acceleration of Tamir's car?

Answer 1

The definition of centripetal acceleration is:

a_c = v²/r

So, let's plug in what we know and solve:

a_c = v²/r

<=> (10m*s^-1)²/20m

a_c = 5m*s^-2
