(b) (c) Or, gives which checks. Reflect: The maximum force and maximum acceleration occur when the displacement is maximum and the velocity is zero. 11.32. Set Up: The fly has the same speed as the tip of the tuning fork. Solve: (a) and (b) 11.33. Set Up: with and Solve: says This gives so Reflect: When the kinetic energy is three times the elastic potential energy. 11.34. Set Up: The total energy is Solve: (a) says E increases by a factor of The new energy will be (b) The new amplitude A is 11.35. Set Up: The period is the time for one cycle. A is the maximum value of x . Solve: (a) From the figure, (b) (c) (d) From the figure, (e) so 11.36. Set Up: When the fish hangs at rest the upward spring force equals the weight mg of the fish. Solve: (a) so (b) Note that T depends only on m and k and is independent of the distance the fish is pulled down. 11.37. Set Up: From Problem 11.35, and Solve: (a) with gives (b) with gives (c) at and at Reflect: At the point in the motion where the speed is a maximum the acceleration is zero and at the point where the magnitude of the acceleration is a maximum the speed is zero.

    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.
