Hookes lay says: , where k is the constant you are looking for, and x the distance the spring is compressed or extended.
Solve for k.
I just sat an exam and wondered if i attempted this question correctly.
it said a spring had force keeping it compressed (i forget the figures) and basically i had to find the modulus of elesticity
so say the force was 800N, would i do this -
or neither... i'm doomed lol
