1. A force of ION causes aspring to extend by 20mm. find A.the spring constant of the spring in N/m
B.the extentsion of the spring in N/m
C. the force applied that causes an externos Of 9mm.​

Respuesta :

Answer:

F = - k x       restoring force for spring constant k

k = F / x = 10 N / .02 m = 500 N / m      force and x are in different directions

B.      N / m = force / distance   given as k

x = F / k = 10 N / 500 N / m = .02 m

C.    F = -k x = 500 N / m * .009 m = 4.5 N
