An object of mass 19.0 kg is hung from a spring with a spring-constant, k = 350 N/m. A chord attached to the spring passes over a frictionless pulley as shown. The object is released from rest and at the moment the object has dropped 0.500 m, the spring is also stretched by 0.500 m from its natural length. What is the speed of the mass at this moment? Give your answer in units of m/s, accurate to 1 decimal place.
