One particle has a mass of 4.59 x 10-3 kg and a charge of +7.03 ?C. A second particle has a mass of 8.88 x 10-3 kg and the same charge. The two particles are initially held in place and then released. The particles fly apart, and when the separation between them is 0.156 m, the speed of the 4.59 x 10-3 kg-particle is 160 m/s. Find the initial separation between the particles.
A simple harmonic oscillator consists of the block of mass 1.90 kg attached to a spring of spring constant 196 N/m. while t = 3.00 s, position and velocity of the block are x = +0.129 m and v = +3.415 m/s.
