While traveling in a car, the centrifugal force a passenger experiences as the car drives in a circle varies jointly as the mass of the passenger and the square of the speed of the car. If the a passenger experiences a force of 100.8 newtons when the car is moving at a speed of 40 kilometers per hour and the passenger has a mass of 70 kilograms, find the force a passenger experiences when the car is moving at 50 kilometers per hour and the passenger has a mass of 80 kilograms.
