Hooke's law for an elastic spring states that the distance a spring stretches varies directly as the force applied. If a force of 100 newtons stretches a spring 5cm, how much will a force of 360 newtons stretch the same thing?
Accepted Solution
A:
We need to write a proportion 1) Force 1/ length 1 =Force 2/ length 2 100 N/ 5 cm = 360 N/ x cm x =5*360/100= 18 cm
2) Proportion can be written also as Length 1/Force 1= Length 2/ Force 2 , and it gives the same result 5 cm/100 N=x cm/360 N x =5*360/100= 18 cm
