take stone 1 total time = x                                                    """" ratio h1/h2= x2/y2   """""

------------2------------= y   initial speed 0 for both

dis in last sec for 1= 1/2* g*(x2-(x-1)2)=1/2*g* (2x-1)= 44.1

--------------------2= 1/2*g* (y2-(y-1)2)=1/2*g* (2y-1)= 63.7

thus find x and y easily

and put the value to get ratio of heights.
