WKT,
U=0
1st stone,
Before 1 sec it travels 44.1m
So, in 1sec at last it travels
S=1/2gt×t
=1/2×9.8×1×1
=4.9
So, total distance from where it released is=44.1+4.9=49
In 2nd stone
u=0
Before one second it travels 63.7 m
So in 1 second at last it travels
S=1/2gt×t
=4.9
So, Total distance from where it release is=63.7+4.9=68.6m
So,the rato is 49:68.6=0.714
