How to find the minimum coefficient of static friction.
To find the coefficient of static friction, we first need to determine the force of friction and the normal force. The force of friction is equal to the applied force (20 N) since the box is not moving. The normal force is the weight of the box, which is the mass (5 kg) multiplied by the acceleration due to gravity (9.8 m/s²).
