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)
