There is a 730g object on a piece of wood measuring 91.5cm. If you slowly lift one end of the wood, predict high would you need to lift it in order for the object move.
The attachment has a picture of what is happening
I have figured that the force of gravity it 7.3N and I have drawn a force diagram. I know how to find all the forces, but i do not know how to tell when the object's force has overcome friction. If someone can tell me how to tell when this happenes, I can solve the rest of the problem by myself. Thank you
