A 14.0-kg chair is at rest on a flat floor. The coefficient of static friction between
the chair and the floor is 0.450. A person tries to move the chair by pushing on the
chair with a force directed at an angle of 30„a below the horizontal. What is the
minimum force that the person must apply in order to move the chair?

    First off the normal force is m*a so 14kg * 9.8 is 137.2N. Since the person isn't pushing straight not all force goes directly to moving the chair. So 137.2=xcos30. x=158.42N.
