Hello i just worked on this problem, Vf^2=Vo^2+2gh
Vf- velocity final
Vo-Initial velocity
g-gravity
h-height
Vf^2=(2.60^2) + 2*(9.8)(8.70)
Vf^2=177.28
square root it... 13.314m/s
Subtract from heli speed, 13.314-2.60= -10.714
negative because up is positive and down well is negative lol
hope it works, that's what i did for my gf homework and she got it right!
Still working on part B sorry :/
A helicopter 8.70 above the ground and descending at 2.60 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 velocity of the package relative to the helicopter.
Vph=
Just as it hits the ground, find the velocity of the helicopter relative to the package.
Vhp=
