A55-kg box rests on a horizontal surface. the coefficient of static friction between the box and the surface is 0.30. a horizontal 42 n force is applied to the box. what is the static friction force on the box? 1) what is the minimum static friction force?
2) how do you calculate the maximum friction force?
3) if an object is at rest before a force is applied at what point does the object starts moving?
