<p>Two inclined planes are placed as shown in figure. A block is projected from the Point A of inclined plane AB along its surface with a velocity just sufficient to carry it to the top Point B at a height 10 m. After reaching the Point B the block slides down on inclined plane BC. Time it takes to reach to the point C from point A is t&nbsp;<span class="equation">\((\sqrt{2}+1)\)</span>s. The value of t is____.&nbsp; &nbsp;(use g = 10&nbsp;<span class="equation">\(m/s^2\)</span>)​​​​​​​</p>
