A certain spring is known to obey Hooke's Law. If a force of 10
newtons stretches the spring 2 meters, how far will a 30 newton force stretch the spring?

Sagot :

Answer: 6 meters

Hooke's law:

Force = - spring constant x extension of spring

Hence spring constant = - force/extension of spring

[tex]\frac{10}{2}=5\frac{n}{m}[/tex]

For force of 30 N, stretch = force/spring constant = [tex]\frac{30}{5}[/tex] = 6 meters
