A car is traveling on a flat circular track of radius 200m at 20 m/s and has a centripetal acceleration a = 4.5m/s² (a) If the mass of the car is 1000 kg, what frictional force is required to provide the acceleration? (b) if the coefficient of static frictions u, is 0.8, what is the maximum speed at which the car can circle the track? Data: Speed of car: v= 30m/s Centripetal acceleration: a = 4.5m/s2 Radius of track: r = 200m Mass of car: m = 1000kg To find: (a) Frictional force: f=? (b) Maximum speed: Vmax=? when us=0.8 A car is traveling on a flat circular track of radius 200m at 20 m/s and has a centripetal acceleration a = 4.5m/s² (a) If the mass of the car is 1000 kg, what frictional force is required to provide the acceleration?
