5. An F1 car of mass 730 kg is traveling around a curve, increasing its speed at a constant rate of 2 m/s². At a given instant, a speed radar reads that the speed of the car on a dangerous turn is 160 km/hr. Given that at this instant, the net force on the car has reached its maximum allowable value of 6000 N, what is the radius of curvature of the turn?
(A) 318 m
(B) 248 m
m = 730
(C) 2840 m
(D) 244 m
(E) 240 m
6000 = 730
