A .35 kg ladle sliding on a horizontal frictionless surface is attached to one end of a horizontal spring (with the spring constant (k) =455 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).
At what riate is the spring doing work on the ladle as the ladle passes through its equilibruim position?
At what raite is the spring doing work on the ladle when the spring is compressed .1m and the ladle is moving away from the equilibrium position?
there was a type-o..but you probably saw it...both questions are suppose to say..at what rate...not raite or riate
