Explanation:
I will assume that you meant that the car's speed was 45 m/ s . (45 m/h could be accomplished by the average turtle.)
With constant speed, the only acceleration must be centripetal acceleration. The formula for centripetal acceleration,
Plugging in the speed,
Let's assume the radius of this curve is 250 m. Then
I hope this helps,
