An object with a mass of 0.5 kg is released at a distance of 2 m, the spring coefficient k = 100 N / m and the object is in the same direction after impact. If it is known to rebound on the road throughout; What is the speed of the object at the moment before it hits the spring? ① The object is 2 m above the arc and is at rest. ② The object is about to hit the spring. ③ It is the moment when the object compresses the spring as much as. ④ It is the moment when the spring is most compressed, the object is at rest at this moment. ⑤ It is the moment when the object loses contact with the spring. ⑥ The object becomes stationary at a distance h from the top of the arc as a result of the recoil from the spring.
