Question

I am so confused! Please Help!
A spring is stretched to a displacement of 30 cm where it experiences a restoring force F. If the spring is then stretched to a displacement of 60 cm , what is the restoring force exerted by the spring

Answer 1

ok, so the recall went like this, hook's law stated the force to be directly proportional to the displacement. if it is not an upper level question then i guess, if not mistakin, the force f would become twice i.e 2f

Answer 2

Thank you so much! Where did you get the 2 from though?

Answer 3

the formula called hooke's first law says that:
"F"(being the restoring force) = "-k"(the spring constant) times "x"(the displacement)
the negative is only for notations sake. and yes this means they are proportional, by means of the constant
so when we double the x we get 2f
