A helicopter 7.60m above the ground and descending at 3.90m/s drops a package from rest (relative to the helicopter). We have chosen the positive positive direction to be upward. The package falls freely.

Question

part A- Just as it hits the ground, find the velocity of the package relative to the helicopter.
Vph=?m/s

part B- Just as it hits the ground, find the velocity of the helicopter relative to the package.
Vph=?m/s

ok for Part A i did 3.9^2+2*9.8*7.6= 164.17 the sqaure root it = 12.812 and i put -12.8 and i got it wrong the formula i used is Vf^2= V1^2+ 2gh i need help please
..

Answer 1

I think your answer is correct.

Answer 2
