A block of mass m = 2.00 kg is attached to a spring of force constant k = 5.65 x 102 N/m that lies on a horizontal frictionless surface as shown in the figure below.. The block is pulled to a position x, = 5.45 cm to the right of equilibrium and released from rest. x= 0 x= x, (a) Find the the work required to stretch the spring. (b) Find the speed the block has as it passes through equilibrium. m/s A block of mass m = 2.00 kg is attached to a spring of force constant k = 5.65 x 102 N/m that lies on a horizontal frictionless surface as shown in the figure below..
