A police officer in hot pursuit drives her car through a circular turn of radius 305 m with a constant speed of 83.5 km/h. Her mass is 55.0 kg. what are the magnitude and the angle of the net force of the officer on the car seat?

There must be a vertical force M g to balance her weight and a horizontal force M V^2/R to provide the centripetal acceleration.
Use the Pythagorean theorem for the magnitude, and the force ration for the tangent of the angle.
