Attached to spring causing it to stretch vertical distance

Reference no: EM13655311

A 400g mass is attached to a spring causing it to stretch a vertical distance of 2cm. The mass is then pulled downward a distance of 4cm and released to vibrate with SHM. What is the spring constant? What is the magnitude and direction of the acceleration when the mass is located 2cm equilibrium position?
