- no ai pleaseA mass m = 7 kg is attached to a spring having a force constant k = 137 N/m as in the figure. The mass is displaced from its equilibrium position and released. What is the angular frequency in rad/s? (please show me the work in detail)You cut the tail spring off and meausre the spring force constaant and determine it to be 42.5 N/m. If you apply a 1.35 kg mass to the spring, what will be the period of oscillation?
