A mass sits on a spring: the spring is attached to the bottom (not the top) of an elevator. Which of the following statements is true? rope O If the mass is accelerating downwards with lal-4 m/s, the spring is extended. O Assuming there are no additional forces acting (as always, assume gravity is present), the maximum acceleration of the mass downwards is 9.8 m/s O If the elevator•mass are moving upwards at constant velocity, the tension in the rope is zero. o the tension in the rope is the same if the elevator•mass are moving at constant velocity, independent of whether the elevator+mass are moving down or up O Two of the above are true O NOTA SPRIN

answer Q 11

**Question 11** **Scenario:** A mass sits on a spring; the spring is attached to the bottom (not the top) of an elevator. **Question:** Which of the following statements is true? **Diagram:** - The diagram depicts an elevator with a rope attached to its top. - Inside the elevator, there is a spring aligned vertically with a red block (representing the mass) resting on it. - The word “SPRING” is written along the spring. **Options:** - ○ If the mass is accelerating downwards with |a| = 4 m/s², the spring is extended. - ○ Assuming there are no additional forces acting (as always, assume gravity is present), the maximum acceleration of the mass downwards is 9.8 m/s². - ○ If the elevator + mass are moving upwards at constant velocity, the tension in the rope is zero. - ○ The tension in the rope is the same if the elevator + mass are moving at constant velocity, independent of whether the elevator + mass are moving down or up. - ○ Two of the above are true. - ○ NOTA (None of the Above)
