This is a job for Newton's 2nd Law! F = ma. We want to know the acceleration, so let's solve it for a, and get a = F/m. Now if we double the force, we'll have a' = 2F/m (where a' is the modified acceleration), and then if we decrease the mass by a half, we'd get a'' = 2F/(1/2*m) = 4F/m. We know the original acceleration was a = F/m, so let's sub that into the a'' equation and get: a'' = 4a, so a'' is 4 times the magnitude of our starting a.

Answer:
The centripetal acceleration of the car doing gentle curve is less than its counterpart of a sharp curve.
Explanation:
A sharp curve would have a lower curvature radius than a gentle curve:
Since the formula for the centripetal acceleration is
with r in the denominator.
if the velocity is the same, and the gentle curve has larger radius, then the centripetal acceleration of the car doing gentle curve must be less than its counterpart of a sharp curve.
