Question

using hooke's law F spring equals K triangle X find the force needed to stretch a spring 2cm if it has an elastic constant of 3 N/cm

Answer 1

Data:

Hooke represented mathematically his theory with the equation:

F = K * x  

On what:

F (elastic force) = ?

K (elastic constant) = 3 N/cm

x (deformation or elongation of the elastic medium) = 2cm

Solving:

$F = K * x$

$F = 3\:\dfrac{N}{\diagup\!\!\!\!\!\!cm}*2\:\diagup\!\!\!\!\!\!cm$

$\boxed{\boxed{F = 6N}}\end{array}}\qquad\checkmark$

Answer:

C. 6 N
