D The next three questions all have to do with the following scenario: A 600 gram box is sliding along a frictionless floor with a speed of 5 m/s when it collides with a horizontal spring that has a spring constant of 150 N/m. Let's use conservation of energy to determine how much the box will compress the spring. Assume the spring was at its relaxed length before the collision. D Question 6 1 pts We should choose our initial moment as v [ Select ] just before the box touches the spring when the spring reaches its maximum compression We should choose our final moment as when the box is at rest before it acquires its 5 m/s speed
