11. Answer: 1 (Range $R = 2\sqrth(H-h)$. If $h=H/4$, $R = 2\sqrt(H/4)(3H/4) = H\sqrt3/2$. Wait, calculating range relative to hole depth is standard, but range from base to landing point on ground is horizontal range. Let's re-evaluate: Time to fall height $(H-h)$ is $t$. Range $x = v_x t$. $v_x = \sqrt2gh$. $H-h = \frac12gt^2$. Range = $\sqrt2gh \times \sqrt\frac2(H-h)g = 2\sqrth(H-h)$. If $h=H/2$, Range is $H$. Here $h=H/4$. Range $= 2\sqrt(H/4)(3H/4) = \frac\sqrt32H$. Ratio to $H$ is $\sqrt3/2 \approx 0.866$.) 12. Answer: 2.014102 u (Mass Defect $\Delta m = 2.2/931.5 \approx 0.00236, \textu$. $M_D = M_P + M_N - \Delta m$.)
