Answer
The answer is below.
Work Step by Step
The acceleration of the spring is 0 when it is located in its unstretched and uncompressed position. After all, we know that F is equal to 0 when the spring is not displaced at all (x is equal to zero). We know that the velocity is 0 when the spring "turns around." This occurs when the spring is fully compressed or when it is fully decompressed.
