First two parts only please. 

A spring with a force constant of 1100 N/m has been compressed by 5 cm.

What is the strength of the force that the spring is exerting?

 N

Be careful about units. The Force Constant was given in N/m, so the displacement must be in meters!
  Incorrect. Tries 1/2 Previous Tries


How much potential energy is stored by the spring?

 J

  Tries 0/2  


If the compression of the spring is doubled, by what factor does the spring force change?
Correct: Two times larger
Incorrect Four times larger
Incorrect Same
Incorrect One half as large

  Computer's answer now shown above. You are correct.
Your receipt no. is 156-9250
