A Imagine a negatively charged particle, A approaching another negatively charged particle, B, along the path shown in the diagram. A moves from point X to point Y. These two particles form an isolated system, which means no work is done by external forces; therefore, the system's total energy does not change. A foelsan clectrical force (an repelling force) from B while it approaches B. Therefore, work is done...

1. An ideal (frictionless) simple harmonic oscillator is set into motion by releasing it from rest at X +0.750 m. The oscillator is set into motion once again from x=+0.750 m, except the oscillator now experiences a retarding force that is linear with respect to velocity. As a result, the oscillator does not return to its original starting position, but instead reaches = +0.700 m after one period. a. During the first full oscillation of motion, determine the fraction of...
