A parachutist fell after releasing himself at 50 m down without any resistance. When the parachute was opened then the rate of decrease the acceleration was \( 2 \mathrm{~m} / \mathrm{s}^{-2} \) and he fell on the ground with velocity of \( 3 \mathrm{~m} / \mathrm{s} \) . At what height he was released?
