A horizontal spring attached to a wall has a force constant of k 700 N m A block of mass m 1 80 kg is attached to the spring and rests on a frictionless horizontal surface as in the figure below ww m x 0 x x 2 x x a The block is pulled to a position x 5 40 cm from equilibrium and released Find the potential energy stored in the spring when the block is 5 40 cm from equilibrium 3 b Find the speed of the block as it passes through the equilibrium position m s c What is the speed of the block when it is at a position x 2 2 70 cm m s
