1A mass of 2 units is in equilibrium suspended from a spring with a springconstant of k = 18. The mass is pulled down 0.5 unit and released. Find theperiod, frequency, and amplitude of the resulting simple harmonic motion.Write the equation of the motion, and graph two cycles of the di...
A mass of 0.20 kg , hung from a spring with a spring constant of 80.0 N/m , is set into an up-and-down simple harmonic motion. If the mass is displaced from equilibrium a distance and released at rest, its speed moving through the equilibrium position is 2.0 m/s. then what is t...
