Final answer:

The friction force on the truck can be calculated using the equation fₛ = μₛ × N, where μₛ is the coefficient of static friction and N is the normal force. Plugging in the given values, we can find the friction force.

Step-by-step explanation:

The friction force on the truck can be calculated using the equation:

fₛ = μₛ × N

Where:

  • fₛ is the friction force
  • μₛ is the coefficient of static friction
  • N is the normal force

Since the truck is parked on a slope, the normal force can be calculated as:

N = mg × cos(θ)

Where:

  • m is the mass of the truck
  • g is the acceleration due to gravity
  • θ is the angle of the slope

Plugging in the given values:

fₛ = μₛ × N = μₛ × mg × cos(θ)
