1. A spring has a natural length of 10 in. An 800-lb force stretches the spring to 14 in.
(a) Find the force constant.
(b) How much work is done in stretching the spring from 10 in. to 12 in.?
(c) How far beyond its natural length will a 1600-lb force stretch the spring

Wouldn't I need to integrate since it doesn't start from 0?

yeah integrate the force time displacement to get the total work
$$W_{0 \rightarrow x} =\int_0^xFdx$$

No I mean would I integrate to get the constant K?

or would it just be 800=4k
