Question

using hooke's law F spring = k Δ x find the force needed to stretch a spring 2 cm if it has elastic constant of 3 N/cm. A. 2/3 N B. 3/2 N C. 6 N D. 3 N

Answer 1

Answer: the elastic constant, a number that tells the relative strength of the spring

Explanation:

Consider Hooke's law can be applied to springs, describing properties such as stretching and/or compression and depends on the material of the spring.

Answer 2

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 (N)/(\diagup\!\!\!\!\!\!cm) * 2\diagup\!\!\!\!\!\!cm`

`\boxed{\boxed{F = 6N}}`

Answer:
C. 6 N
