Answer:

I don't know how to do it the subject

The centripetal acceleration of the car when there is the radius and the speed is given so it should be considered as the option b. 36 [tex]m/s^2[/tex].

Calculation of the centripetal acceleration of the car:

Since

The radius is 25 cm and the speed should be 30 m/s

Now the following formula should be used

Acceleration = speed^2/ radius

= 30^2 / 25

= 900 / 25

= 36 [tex]m/s^2[/tex]

Therefore, The centripetal acceleration of the car should be considered as the option b. 36 [tex]m/s^2[/tex].
