A flat (unbanked) curve on a highway has a radius of 240 m . A car successfully rounds the curve at a speed of 37 m/s but is on the verge of skidding out. Part A If the coefficient of static friction between the car’s tires and the road surface were reduced by a factor of 2, with what maximum speed could the car round the curve? Express your answer in meters per second to two significant figures. part B...
