Your answer is partially correct.

The figure shows block $1$ of mass $0\mathrm{.}270$ kg sliding to the right over a frictionless elevated surface at a speed of $7\mathrm{.}70\frac{m}{s}.$ The block undergoes an elastic collision with stationary block $2,$ which is attached to a spring of spring constant $1104\frac{N}{m}.($Assume that the spring does not affect the collision.$)$ After the collision, block $2$ oscillates in SHM with a period of $0\mathrm{.}175$ s $,$ and block $1$ slides off the opposite end of the elevated surface, landing a distance $d$ from the base of that surface after falling height $h=6\mathrm{.}40m.$ What is the value of $d?$
