1). A 0.20 kg mass resting on a frictionless surface is attached to a solid wall by means of a spring with and elastic force constant k of 5.0 N/m. The mass is displaced horizontally from equilibrium a distance of 10.0 cm and released, whereupon the mass undergoes simple harmonic motion. Calculate the following:
a. the oscillation frequency.
b. the total energy of the oscillation.
c. the maximum velocity experienced by the mass.
