A person with mass of 70kg is climbing a ladder with a length of 6 m and the ladder has a mass of 20kg that leans against a smooth, frictionless wall. A frictional force between the ladder and the floor keeps it from slipping. The angle between the ladder and the wall is 30 degrees - What is the magnitude of the frictional force of the floor so that the person can reach the top of the ladder?
