A 4500 kg truck is parked on a 7.0 degree slope. How big is the friction force on the truck?
♦ Relevant knowledge
In accordance with Newton’s Second Law, force exerted on an object is calculated as the combination of the mass and the velocity of an object. In the event that the object remains stationary the force it exerts on it will be negligible. If the object isn’t in moving, then static friction is likely to occur, and the kinetic friction takes place.
