We consider a harmonic oscillator consisting of a spring with spring constant k , connected to a wall at one end and a mass m 1 at the other. The mass can move along the xaxis as indicated. The coordinate of the mass is such that x = 0 when the spring is without tension. At time t = 0 the mass is at rest at x = 0 . At this time ( t = 0 ) another mass m 2 m 1 hits m 1 with velocity v 2 . The quantities listed here are considered known. 1. We assume that there is no friction between m 1 and the horizontal surface, and that the collision between m 1 and m 2 is instantaneous and inelastic such that the two masses move as one after the collision. a. Express the velocity u 12 of the united object immediately after the collision, and calculate the loss in kinetic energy during the collision....
