Friction – Practice
1) A pet owner attempts to pull his reluctant dog out the front door. The co-efficient of friction between the dog and the floor is 0.35. The owner pulls on the dog with a force of 50N. Determine the force acting on the dog after friction has been considered.
2) A removalist pushes a lounge along his truck with a force of 100N. The resultant force after the friction of the truck is considered is 72N. What is the coefficient of friction in this example?
1) 32.5N in the direction the owner is pulling the dog!
2) μ = 0.28
