A rescue helicopter drops a 10 kg package of emergency supplies to hikers stranded in the rocky valley. The chopper velocity has horizontal component due east at 1 m/s and a vertical component 2 m/s. The pilot drops the package from a height of 30 m above the ground. The acceleration due to gravity is 9.81 m/s2. Where does the package strike the ground relative to the point where it was released? What is the kinetic energy of the package...

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....

PRACTICE IT Use the worked example above to help you solve this problem A ball is thrown upward from the top of a building at an angle of 30.0° to the horizontal and with an initial speed of 22.0 m/s. The point of release is h41.0 m above the ground (a) How long does it take for the ball to hit the ground? (b) Find the ball's speed at impact. m/s (c) Find the horizontal range of the ball

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
