A `5 kg` rod of square cross section `5 cm` on a side and `1m` long is pulled along a smooth horizontal surface by a force applied at one end. The rod has a constant acceleration of `2 ms^(-12)`. Determine the elongation in the rod. (Young's modulus of the material of the rod is `5 xx 10^(3) N//m^(9)`).
