How fast is a moving object when it has won all the springs "original stored energy?

An object of 1 kg at a time, horizontal bench press without friction against a constant force spring 100N / m and then released. Just before the object is released, the spring 0.3m is compressed. How fast is the object that moves when you've won all the original sources of stored energy? a. 2 m / s b. 3 m / s c. 5 m / sd 1 m / S e. 10m / s

I think it has to conserve energy. PE_0 = KE_f PE of a spring = 0.5 * k * x ^ 2 = 0.5 * 100 * 0.3 ^ 2 = 4.5, where k is the spring constant and x is the distance in meters KE = 0.5 * m * v ^ 2 which set equal to each other and solve for v
