A rock thrown with speed $11\mathrm{.}0$m$/$sm$/$s$$and launch angle $30\mathrm{.}0($above the horizontal$)$ travels a horizontal distance of$$dd$=19\mathrm{.}5$mm$$before hitting the ground. From what height was the rock thrown? Use the value$$gg$=9\mathrm{.}800$m$/$s$2$m$/$s$2$for the free$-$fall acceleration.A second rock is thrown straight upward with a speed $5\mathrm{.}500$m$/$sm$/$s$.$ If this rock takes $2\mathrm{.}047$ss$$to fall to the ground, from what height$$HH$$was it released? $$
