A helicopter above the ground is descending at 3.5m/s. It drops a package from rest (relative to the helicopter). Just before it hits the ground the package is falling at a rate of 13.4m/s relative to the ground. Find the velocity of the package relative to the helicopter.
A. 9.9m/s, up
B. 9.9m/s, down
C. 16.9m/s, down
D, 16.9m/s, up
