Answers
Answer:
Spring force is the force that try to restore the original shape of the spring. When you stretch a spring you change it's configuration. And trust me spring doesn't like that. How do I know that the spring doesn't like that ? That's because as soon as you will remove the force that you are applying on the spring the spring will immediately try to regain it's original shape.

Answer:
The work done of a mechanical arrangement is the dot product of applied force and the displacement due to the applied force. If a spring is stretched, the direction of applied force and the direction of displacement are the same. And the angle between the force and the displacement is zero, which results in the positive work done by the stretching force.
