A block of unknown mass is attached to a spring of spring constant 7.9 N/m and undergoes simple harmonic motion with an amplitude of 13.2 cm. When the mass is halfway between its equilibrium position and the endpoint, its speed is measured to be 28.9 cm/s.
Calculate the mass of the block. Answer in units of kg
