Part A

Identify and sketch all the external forces acting on the chair. Because the chair can be represented as a point particle of mass \( m \). draw the forces with their tails centered on the black dot in the middle of the chair. Be certain to draw your forces so that they have the correct orientation.
Draw the vectors starting at the black dot. The location and orientation of the vectors will be graded. The length of the vectors will not be graded.

Apply these steps
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=55.0 kg across a carpeted floor with a force F⃗p (the subscript 'p' here is lowercase and throughout the question) of magnitude Fp =160 N directed at θ=35.0 degrees below the horizontal (Figure 1). The magnitude of the kinetic frictional force between the carpet and the chair is Fk= 107 N .

Part A

Identify and sketch all the external forces acting on the chair. Because the chair can be represented as a point particle of mass m. draw the forces with their tails centered on the black dot in the middle of the chair. Be certain to draw your forces so that they have the correct orientation.
Draw the vectors starting at the black dot. The location and orientation of the vectors will be graded. The length of the vectors will not be graded.
