When you compress or stretch a spring, as soon as the stress is relieved, the spring attains its normal shape instantly. Its Elastic potential energy helps it do so. Generally, these elastic substances follow the Hooke’s law.

According to this Law, the force needed to change the shape of spring is proportional to the displacement of the spring. The displacement referred here is how far the spring is compressed or stretched from its normal shape. Mathematically, Hook’s Law can be summarised as F= – k x. Here ‘k’ is the spring constant and ‘x’ is the displacement.

                                                               Father           Son

5years ago the age of the father & son           5X                X

present the age of the father & son              5X+5             X+5

(present age of father) + (present age of son) = 70

       (5x+5)                 +        (x+5)              = 70

 Then you will get X = 10

Present age of the son (x+5) = 15
