Answer:

3.75 m/s^2

Explanation:

The centripetal acceleration of an object in uniform circular motion is given by the equation:

$a=\frac{v^2}{r}$

where

v is the tangential speed of the object

r is the radius of the trajectory

In this problem, r = 60 m and v = 15 m/s, therefore the centripetal acceleration of the car is

$a=\frac{(15 m/s)^2}{60 m}=3.75 m/s^2$
