A spring has a spring stiffness constant k of 75.0 N/m. How much must this spring be compressed to store 25.0 JJ of potential energy?

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

be subject to a force andchange its motion

compass can be used day and night, cloudy or sunny

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
