Any help at how to tackle this problem would be appreciated. I know it involves using a string of kinematic equations, but I'm having trouble with the velocity.

well its quite simple. ... take the vel of package in the backward hor. dir to b v=8.1+13=21.1m/s

H=16m

16=1/2*9.8*t*t evaluate t from this eqn.

d1=diatance traveled by the package in the hor. dir=v*t

d2=dist. traveled by the helicopter in the hor. dir.=8.1*t

hor. dist. bet the two when the package hits ground=d1+d2.

bye
