Given information
Given that a force of 35N is required to move a box from rest on a horizontal floor and the mass of the box is
The coefficient of static friction
Step-by-step explanation
Step 1.
Static friction is the force that keeps the object at rest and is equal to the static friction coefficient times the normal force. For the object to move, the force applied to the object must overcome the static friction.
Given that the force applied to move the box is , we can say that the magnitude of the static frictional force is equal to the applied force.
i.e.; frictional force .
