You are driving a Porsche carrera GT on straight testing track at a constant speed of150kmh. you pass a 1971 volkswagen beetle doing a constant 75 kmh. for which car is the net force greater justify y?

The net force on both cars is the same. According to Newton's third law of motion, the force exerted by the Porsche on the Beetle is equal in magnitude and opposite in direction to the force exerted by the Beetle on the Porsche. Therefore, both cars experience the same net force.
