Karen is driving on the 210 freeway in her 3,500 kg Escalade when she sees Hayley driving a Tesla on the street next to the freeway. Karen immediately h the off ramp, which has a radius of curvature of 35 m, so she could catch her. If the coefficient of friction between the road and Karen's tires is 0.8, what is fastest speed Karen can travel and safely make the turn? O 10.4 m/s O 16.6 m/s 26.3 m/s O 30.2 m/s

This is a problem of motion in a circular curve. In this case, Karen's tires must exert a frictional force on the surface of the road in order to provide the required centripetal force for the safe negotiation of the curve.
