It is true that there are two types of addiction, psychological and
physical. When it comes to physical addiction, it normally refers to
drug withdrawal or drug usage, when your body is exhibiting various
symptoms of needing drugs. Mental addiction refers to when there is no
actual need to use the object of addiction, but rather a mental desire
to use it and have it again.

Answer:
K = 36 J
Explanation:
In this exercise we must use the conservation of mechanical energy at two points at initial x = 0 and the end point of maximum compression of the spring
Initial x = 0
     Em₀ = K = ½ m v²
Final point of maximum compression
      = Ke = ½ k x²
 = Ke = ½ k x²
     Em₀ = 
     K = ½ k x²
We put the kinetic energy because it is a data, let's look for the spring constant
      k = 2 K / x²
      k = 2 9 / d²
      k = 18 / d²
Let's calculate the kinetic energy, so that the compression is x = 2d
     K = ½ k x²
     K = ½ (18 / d²) (2d)²
     K = ½ 18/d²  4d²
     K = 36 J
