A 0. 20 kg object, attached to a spring with spring constant k = 10 n/m, is moving on a horizontal frictionless surface in a simple harmonic motion of amplitude of 0. 080 m. What is the its speed at the instant when its displacement is 0. 040 m? (hint: use conservation of energy. ).

James needs to move this box. he has already checked it and knows it is not too heavy for him to lift. he also has a clear path and a place to safely set down the box. tell james what to do next to safely lift this box by placing the steps in the correct order. place the options on the left in the correct sequence by dragging them to the appropriate answer box to check your answer.
