A 4 kg4 \mathrm{~kg} roller is attached to a massless spring of spring constant k=100 N/mk=100 \mathrm{~N} / \mathrm{m}. It rolls without slipping along a frictionless horizontal road. The roller is displaced from its equilibrium position by 10 cm10 \mathrm{~cm} and then released. Its maximum speed will be
