(A) For a body thrown horizontally from a height $H$ with velocity $v$,the horizontal range $R$ is given by $R = v \sqrt{\frac{2H}{g}}$.Given for the first case: $100 = v \sqrt{\frac{2H}{g}}$.For the second case,the mass is $2M$,the velocity is $v' = \frac{v}{2}$,and the height is $H' = 4H$.The new horizontal range $x$ is given by:$x = v' \sqrt{\frac{2H'}{g}} = \left( \frac{v}{2} \right) \sqrt{\frac{2(4H)}{g}}$$x = \frac{v}{2} \cdot 2 \sqrt{\frac{2H}{g}} = v \sqrt{\frac{2H}{g}}$Since $v \sqrt{\frac{2H}{g}} = 100 \ m$,we get $x = 100 \ m$.
