Answer;

  = 64 N/m

Explanation;

According to Hooke's Law for a helical spring or an elastic material, extensional force is directly proportional to the distance the material has extended.

F = ke; where F is the extension force, k is the spring constant, and e is the distance extended.

Thus;

k = F/e

  = 44N/0.69 m

  = 63.768 N/m

  = 64 N/m
