A car is driving around a banked, circularly curved road with a radius of 4.78 X 102 m. The mass of the car is 1506 kg, and the road Is banked at an angle of 21". (a) Ignoring friction, what is the maximum speed the car can have without slipping? _x Your response differs from the correct answer by more than 10%. Double check your calculations. m/s (b) What is the magnitude of the centripetal force on the car if it were to travel at the maximum speed around the track? _x Your response differs from the correct answer by more than 10%. Double check your calculations. N (c) Would including friction in this problem increase the maximum speed allowed or decrease it? Explain your answer. i 0 Adding friction would increase the maximum speed allowed since there would he an additional force contributing to the centripetal force, helping accelerate the car towards the center of i motion and reducing the chance that the car will siide off of the track. i 0 Adding friction would decrease the maximum speed allowed since there would be an additional force contributing to the centripetal force, helping decelerate the tar towards the center of motion and reducing the chance that the car will slide off of the track
