1.) Pushing on the pump of a soap dispenser compresses a small spring. When the spring is compressed 0.45 {\rm cm}, its potential energy is 0.0030 {\rm J}.
a.) What is the force constant of the spring?
b.) What compression is required for the spring potential energy to equal 0.0094 {\rm J}?
2.) The force required to flex a nasal strip and apply it to the nose is 0.25 {\rm N}; the energy stored in the strip when flexed is 0.0025 {\rm J}. Assume the strip to be an ideal spring for the following questions.
a.) Find the distance through which the strip is flexed.
b.) Find the force constant of the strip.
