Ladle Attached to Spring A 0.23 kg ladle sliding on a horizontal frictionless surface is attached to one end of a horizontal spring (with k = 490 N/m) whose other end is fixed. The mass has a kinetic energy of 10 J as it passes through its equilibrium position (the point at which the spring force is zero).(adsbygoogle = window.adsbygoogle || []).push({});

(a) At what rate is the spring doing work on the ladle as the ladle passes through its equilibrium position?

i got this correct: 0 watts

(b) At what rate is the spring doing work on the ladle when the spring is compressed 0.10 m and the ladle is moving away from the equilibrium position?
