A helicopter 8.40 m above the ground and descending at 3.90 m/s drops a package from rest (relative to the helicopter). We have chosen the positive positive direction to be upward. The package falls freely. Just as it hits the ground, find the y -component of the velocity of the package relative to the helicopter. Express your answer in meters per second. Just as it hits the ground, find the y -component of the velocity of the helicopter relative to the package. Express your answer in meters per second. Just as it hits the ground, find the y -component of the velocity of the helicopter relative to the package. Express your answer in meters per second.
Homework Answers
PS we choose negative sign in Vf because final velocity is downward direction.
Explanation: Helicopter is descending downward, so when the object is thrown from helicopter, it has same initial velocity as the helicopter (3.9m/s) and only gravitational force is acting so acceleration is only due to gravity , so final velocity will be directly download. We used kinematics equation in downward direction and calculated final velocity

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...
