A body with mass m = 1/2 kg is attached to end of spring that is streched 2 meters (m) by a force of 100 newtons (N). It is set in motion with initial position X0 = 1 m and initial velocity V0 = -5 m/s. (note that these initial situations indicate that the body is displaced to the right and is moving to the left at time t = 0.) determine the position of the body as well as the amplitude, frequency, period of oscillation, and time of lag motion.
