Compute all parts of given question:
Question: A helicopter 9.00m above the ground and descending at 4.10m/s drops a package from rest (relative to the helicopter). We have chosen the positive direction to be upward. The package falls freely.
Part I: Just as it hits the ground, find the y-component of the velocity of the package relative to the helicopter.
(m/s)
Part II: Just as it hits the ground, find the y-component of the velocity of the helicopter relative to the package.
(m/s)
Don't just give me the answer, explain your steps as well.
