Problem Solving: Free-Body Diagrams and Newton's Laws 1. Draw a sketch of the situation. 2. Consider only one object [at a time}. and draw a freebody diagram for that body, showing all the forces acting on that body. Do not show any forces that the body exerts on other bodies. |f several bodies are involved. draw a freebody diagram for each body separately, showing all the forces acting on that body. 3. Newton's second lay.r involves vectors, and it is usually important to resolve 1vectors into components. Choose an x and y axis in a way that simplies the calculation. 4. For each body. Newton's second law can be applied to the x and y components separately. That is the x component of the net force on that body will be related to the 1: component of that body's acceleration: BF: = m, and similady for the y direction. 5. Solve the equation or equations for the unknownfs}. 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 Fy acting on the chair: Yusef pushes a chair of mass m = 55.0 kg across a carpeted floor with a force Fo (the subscript 'p' here is lowercase and throughout the question) of magnitude F, = 156 N directed at 0 = 35.0 degrees below the horizontal (Figure 1). The magnitude of the kinetic frictional force between the carpet and the chair is F = 107 N .Identity and sketch all the extemal forces acting on the chair. Because the chair can be represented as a point particle of mass m. draw.r 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. [IlrmnlI the vectors starting at the black dot. The location and orientation oi the sectors will be graded. The length of the vectors will not be graded. When solving problems involving forces and Newton's laws, the following summary of things to do will start your mind thinking about getting involved in the problem at hand. Figure
