Question

If a certain spring stretches 4.32221 cm when a load of 15.3617 N is suspended from it, how much will the spring stretch if it is cut in half and 18.2451 N is suspended from it?

Answer 1

each half of the spring had the same force, but only stretched 1/2 the distance originally.

so if you cut it in half, the
original half spring k=15.3617/(.5*4.32221)

new stretch=19.2451/k=18.2451*.5*4.33221/15.3617 about 2.3cm in my head. Work it out.
