The magnitude of the centripetal acceleration of the car as it goes round the curve is 4.8 m/s²
<h3>Circular motion</h3>
From the question, we are to determine the magnitude of the centripetal acceleration.
Centripetal acceleration can be calculated by using the formula

Where
is the centripetal acceleration
is the velocity
and
is the radius
From the given information

and 
Therefore,



Hence, the magnitude of the centripetal acceleration of the car as it goes round the curve is 4.8 m/s²
