Answer :
$a_c=40500\ mi/h^2$ .

Explanation :

It is given that,

Velocity of a race car, v = 135 mi/hr

Radius of the track, r = 0.45 miles

We know that the centripetal acceleration is defined as :

a_c=(v^2)/(r)

r is the radius of the circle.

$a_c=((135\ mi/hr)^2)/(0.45\ mi)$

$a_c=40500\ mi/h^2$

So, the centripetal acceleration of the car is
$a_c=40500\ mi/h^2$ .

Hence, this is the required solution.
