Use the steps outlined above to find the magnitude of the acceleration a of a chair and the magnitude of the normal force Fn acting on the chair: Yusef pushes a chair of mass m = 50.0 kg across a carpeted floor with a force Fp (the subscript p here is lowercase and throughout the question) of magnitude Fp = 148 N directed at = 35.0 degrees below the horizontal (Figure 1). The magnitude of the kinetic frictional force between the carpet and the chair is Fk = 97.8 N. What is the magnitude of the acceleration a of the chair? What is the magnitude of the normal force Fn acting on the chair
