a. Fc = (m * v^2) / R
where m is the mass of the vehicle, v is the velocity of the vehicle, and R is the radius of the curve.
Plugging in the values, we get:
Fc = (1630 kg * (13.9 m/s)^2) / 385 m
Fc = 8206.73 N
Therefore, the centripetal force exerted on the vehicle is 8206.73 N.
b. The force that plays the role of the centripetal force in this case is the force of static friction.
