WebStatic friction is given by the formula: = 90 N. Therefore, the static friction will be 90 N. Q.2: A person is pushing a toy car of mass 4 kg which was at rest position on the floor. If 100 N is the value of the static frictional force, then determine the friction coefficient? Answer: Known values are as, Mass, m = 4 kg, Static frictional force, WebFor an object at rest on a flat table, static friction is zero. If you push horizontally with a small force, static friction establishes an equal and opposite force that keeps the book at rest. As you push harder, the static friction force increases to match the force. Eventually maximum static friction force is exceeded and the book moves.
