Question

given that the 180N weight causes a total extension of 30cm ,determine the spring constant of each spring (the weight of each spring is neglible)​

Answer 1

Answer:600N/m

Explanation:  Given ;

                       Applied force(F) = 180N

                      Total extension (l) = 30cm =0.30m

                       Spring constant(K) =?

                       From Hooke's law

                         F= kx

                        therefore k= F/x

                                  k = 180N/0.3m

                                    600N/m
