A 1380-kg racecar is driving around a circular track of radius 157 m. In the instant shown in the figure, the vehicle has a forward speed of 29.1 m/s and is slowing at a rate of 5.75 m/s^2. What is the magnitude of the net force acting on the vehicle at this time and the force's direction relative to the velocity?
