## To solve this problem, we need to consider the forces acting on the cable and use Newton's second law of motion.

Let's start by identifying the forces acting on the cable. There are two main factors to consider:

1) The weight of the car: The weight of the car and its occupants adds to the tension in the cable. It can be broken down into two components: the vertical component mg, where m is the mass of the car, and g is the acceleration due to gravity, and the component mg*sin(Î¸), where Î¸ is the angle of incline.

2) The acceleration of the car: As the car is being accelerated up the incline, there is an additional force due to the mass of the car multiplied by the acceleration (ma).

To find the difference in tension between adjacent sections of the pull cable, we need to calculate the total tension in each section. The equation that relates these forces is:

Total tension = ma + mgsinÎ¸

Where:

m is the mass of the car

a is the acceleration of the car

g is the acceleration due to gravity (approximated as 9.8 m/s^2)

Î¸ is the angle of incline (35 degrees in this case)

By plugging in the given values for the mass (2800 kg), the acceleration (0.81 m/s^2), and the angle of incline (35 degrees), you can solve for the total tension in each section of the pull cable. The difference in tension between adjacent sections can be found by subtracting the tension of the lower section from the tension of the higher section.
