can we get its velocity after the collar moved to 1m

why did u multiply 0.5 to 3? isnt it supposedly 3(1.25)?

[@engineeringdeciphered]

The force in a spring is k(x) where x is the “stretch” of the spring, not the length of the spring. So if the current length is 1.25 and the unstretched length is 0.75, that means it is being stretched by 0.5. [x is length minus unstretched length]
