1. The problem statement, all variables and given/known data A 6.0 kg box moving at 3.0 m/s on a horizontal, frictionless surface runs into a light spring of force constant 75N/cm. Use the work energy theorem to find the maximum compression of the spring. 2. Relevant equations Wtotal=K2-K1 k1=1/2mv^2=27 J 3. The attempt at a solution I mus tbe missing something conceptually here, this doesn't appaear to be a difficult problem but I just don't know how to approach it. I don't know the total work, how do I find it?
