A car with a constant speed of 83.0 km/h enters a circular flat curve with a radius of curvature of 0.400 km. If the friction between the road and the car's tires can supply a centripetal acceleration of 1.25 m/s^2, does the car negotiate the curve safely? Justify the answer.© BrainMass Inc. brainmass.com March 4, 2021, 6:15 pm ad1c9bdddf
v = 83 kmph = 83*5/18 m/s = 23.055 m/s
r = 0.400 km = 400 m
The expert examines uniform circular motion and centripetal acceleration.
