PRACTICE IT Use the worked example above to help you solve this problem. A water hose 2.15 cm in diameter is used by a gardener to fill a 31.0-liter bucket. (One liter = 1,000 cm.) The gardener notices that it takes 1.00 min to fill the bucket. A nozzle with an opening of cross-sectional area 0.500 cmis then attached to the hose. The nozzle is held so that water is projected horizontally from a point 1.00 m above the ground....

3) Zana was flying a rescue plane (horizontally) when she spots a survivor directly below and releases an emergency kit with a parachute. If the package descends at a constant vertical acceleration of magnitude 4.27m/s2 and the initial place horizontal speed was 72.3 m/s, how high was the plane when it released the package hits the water 731 m away from the survivor? Please use a lot of details when explaining
