Yusef pushes a chair of mass m = 55.0kg across a carpeted floor with a force F? p (the subscript 'p' here is lowercase and throughout the question) of magnitude Fp = 148N directed at ? = 35.0degrees below the horizontal (Figure 1) . The magnitude of the kinetic frictional force between the carpet and the chair is Fk = 106N .
What is the magnitude of the acceleration a of the chair?
What is the magnitude of the normal force FN acting on the chair?
