A mass of 0.5 kg moving along a horizontal frictionless surface encounters a spring having k = 200 N/m. The mass compresses the spring by 0.1 meters before reversing its direction. Consider the total time the mass is in contact with the spring. What is the total impulse delivered to the mass by the spring?

  1. -4 N-s
  2. -2 N-s
  3. 0 N-s
  4. 2 N-s
  5. 4 N-s
  6. none of the above
  7. cannot be determined.
