Answer:

11,140.33 N

Explanation:

  • Normal force refers to the force exerted on a body or an object by a surface.
  • Normal force is calculated by the formula;
  • [tex]Normal force = MgCos\beta[/tex], where m is the mass, g is the gravitational acceleration and [tex]\beta[/tex] is the angle of inclination.

In this case;

Mass = 1150 kg

β = 8.70°

But, g = 9.8 m/s²

Therefore;

Normal force = 1150 kg × 9.8 m/s² × cos 8.70°

                     = 11,140.33 N

Thus, the normal force on the car is 11,140.33 N
