Question

A 1150 kg car is on a 8.70 hill. what is the normal force on the car?​

Answer 1

11,140.33 N

Step-by-step explanation:

• Normal force refers to the force exerted on a body or an object by a surface.
• Normal force is calculated by the formula;

• 
  `Normal force = MgCos\beta`, where m is the mass, g is the gravitational acceleration and
  `\beta` 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
