5.12. Set Up: Use coordinates with upward and to the right. Label the tensions and Solve: (a) The free-body diagram for the officer is given in Figure 5.12. Each tension is replaced by its x and y components. Figure 5.12 (b) gives gives and Then 5.13. Set Up: Apply to the ball. Since the post is frictionless, the force it exerts on the ball is a horizontal normal force. Use coordinates with upward and to the right. Solve: The angle between the string and post can be calculated from Figure 5.13a. l is the length of the string and r is the radius of the ball. and Figure 5.13 (a) The free-body diagram of the ball is given in Figure 5.13b.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
