wwwwww Ax A 0.8kg box on a horizontal frictionless surface is moving to the right at a speed of 2.19m/s. The box hits and remains attached to one end of a spring of negligible mass whose other end is attached to a wall. As a result, the spring compresses a maximum distance of 4cm, and the box then oscillates back and forth. Think: the spring does work on the box from the moment the box first hits the spring to the moment the spring first reaches its maximum compression. Indicate whether the work done by the spring is positive. negative, or zero. Calculate the magnitude (absolute value) of this work.
