HW Chapter 13 and Chapter 14 13.6 In a physics lab, you attach a 0.200-kg air-track glider to the end of an ideal spring of negligible mass and start it oscillating. The elapsed time from when the glider first moves through the equilibrium point to the second time it moves through point is 2.60 s. Find the spring force constant. 13.19 A 1.50-kg mass on a spring has displacement as a function of time given by the equation x(t) = (7.40 cm) cos [(4.16 s -1 )t – 2.42]. Find a) the time for one complete vibration; b) the force constant of the spring; c) the maximum speed of the mass; d) the maximum force on the mass; e) the position, speed, and acceleration of the mass at t = 1.00 s, and the force on the mass at that time. 13.44 A small sphere of mass m is attached to a massless rod of length L that is pivoted at the top, forming a simple pendulum. The pendulum is pulled to one side so that the rod is at an angle θ from the vertical, and released from rest. a) In a diagram, draw vectors representing the forces acting on the small sphere and the

    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.
