... Conceptual Example 8 Changing the Mass of a Simple Harmonic Oscilator The box rests on a horizontal, frictionless surface. The spring is stretched to x=A and released. When the box is passing through x=0, a second box of the same mass is attached to it. Discuss what happens to the (a) maximum speed, ...

... In step 4 of Exploration 11.6, we stated that the angular momentum of the system consisting of Sarah and the merry-go-round was conserved, because no external torques were acting on the system. Let’s justify that statement. We do not have to concern ourselves with vertical forces, such as the force ...
