Use the steps outlined above to find the magnitude of the acceleration of a chair and the magnitude of the normal force acting on the chair: Yusef pushes a chair of mass = 55.0 across a carpeted floor with a force (the subscript 'p' here is lowercase and throughout the question) of magnitude = 156 directed at = 35.0 below the horizontal . The magnitude of the frictional force between the carpet and the chair is = 107 .
