Answer

Answer:

C. The net force on the car is greater than zero in the horizontal direction.

Explanation:

Step1: Recall Newton's second law

$F = ma$, where $F$ is net - force, $m$ is mass and $a$ is acceleration.

Step2: Analyze the vertical direction

In the vertical direction, the car is on a flat and level road. The gravitational force ($mg$) acting downwards is balanced by the normal force ($N$) acting upwards. So, $N - mg=0$, and the net - force in the vertical direction $F_y = 0$.

Step3: Analyze the horizontal direction

When Gina presses the gas pedal, the car starts to accelerate (speed up) in the horizontal direction. According to Newton's second law ($F = ma$), since the car has a non - zero acceleration ($a_x>0$) in the horizontal direction and mass ($m>0$), the net force in the horizontal direction $F_x=ma_x>0$.
