Use Hooke's Law for springs, which states that the distance a spring is stretched (or compressed) varies directly as the force on the spring.
A force of 265 newtons stretches a spring 0.15 meter.
(a) What force is required to stretch the spring 0.2 meter? (Round your answer to two decimal places.)
Incorrect: Your answer is incorrect. .
N
(b) How far will a force of 100 newtons stretch the spring? (Round your answer to two decimal places.)
m

since d/F is constant,
.15/265 = .2/x
and,
.165/265 = x/100
Note that you don't really have to find k, the constant of proportionality. You can go ahead and find it, but your answers will be the same.
