A horizontal spring has a force constant 7.98 N/m and is attached to a wall at one end. A block of wood ofmass 366 g is attached to the the other end. We assume that this system sits on a frictionless surface.The block is displaced by +6.90 cm from equilibrium and released from rest.a. What is the period of the motion?Sb. What is the equation that describes the position of the block?
