1. Work of 2 Joules is done in stretching a spring from its natural length to 16 cm beyond its natural length. What is the spring constant ?
    Don't forget to enter the correct units.

  2. If the spring is stretched to the same distance (16 cm), what is the restoring force that pulls the spring back toward its equilibrium position?
    Restoring force = Don't forget to enter the correct units.
