Question

The spring in a toy rocket launcher has a spring constant of 13 N/m. How far must you compress the spring to cause it to exert a force of 2.5 N?

Answer 1

(2.5/13)= 0.192  is your Answer

Answer 2

Answer:

Distance, x = 0.19 meters

Explanation:

It is given that,

Spring constant of the toy rocket, k = 13 N/m

Force applied on the spring, F = 2.5 N

We have to find the spring constant of the spring. It can be calculated using Hooke's law as :

F = - kx

$x=\dfrac{F}{k}$

$x=\dfrac{2.5\ N}{13\ N/m}$

x = 0.19 meters

Hence, the spring must be compress to cause it to exert a force of 2.5 N.
