In an arcade game a 0.135 kg disk is shot
across a frictionless horizontal surface by compressing it against a spring and releasing it.
If the spring has a spring constant of
155 N/m and is compressed from its equilibrium position by 7 cm, find the speed with
which the disk slides across the surface.
Answer in units of m/s
