Conservative forces and potential energy.

The 2-kg collar is given a downward velocity of 4 m/s when it is at A. If the spring has an unstretched length of 1 m and a stiffness of k = 30 N/m, determine the velocity of the collar at s = 1 m.

Thank you so much! I have been trying to solve it from Force times distance, and it was hell. xD

Hello, wanted to ask if the formula for spring force is 1/2 * k * (s2^2 - s1^2)?
