A chair of mass 12.0 kg is sitting on the horizontal floor; the floor is not frictionless. You push on the chair with a force F = 45.0 N that is directed at an angle of 38.0 degrees below the horizontal and the chair slides along the floor. Use Newton's laws to calculate the normal force that the floor exerts on the chair. Please see images, for previous incorrect answers and hints. Submitted AnswersANSWER 1:n= 89.89 NYou may have incorrectly determined the projection of your force on the vertical. Note that the applied force is directedbelow the horizontal.ANSWER 2:n = -89.89 NANSWER 3:n= 117.6 NIt seems that you have considered this angle to be the angle of inclination of the plane along which the chair slides. Notethat the applied force is directed at the given angle below the horizontal.ANSWER 4:n = -117.6 NANSWER 5:n = 90.02 N ANSWER 5:n = 90.02 NYou may have incorrectly determined the projection of your force on the vertical. Note that the applied force is directedbelow the horizontal.ANSWER 6:n = -90.02NANSWER 7:n = 102.55 NANSWER 8:n = 117.72 NIt seems that you have considered this angle to be the angle of inclination of the plane along which the chair slides. Notethat the applied force is directed at the given angle below the horizontal.
