A 0.425-kg mass is attached to a spring of force constant 134.25 N/m and rests on a horizontal, frictionless surface as shown in the figure below. You apply a horizontal force to the mass that causes the spring to stretch 7.64 cm from its equilibrium position before releasing the mass, allowing it to oscillate in simple harmonic motion. Ax F ECA. D|B. a. Determine the magnitude of the force you apply to the mass. F = N. b. What magnitude force does the spring provide before the mass is released? F = N C. What is the magnitude of the acceleration of the mass at the moment the mass is released? a = m/s
