A parcel is connected to a flying drone as illustrated above. Note that the coordinate system is given
with +y pointed in the upwards direction. Holding the parcel, the drone takes off moving straight up
with a velocity of 8.40. m/s. Note that, as usual, y = 0 at the ground.
After 8.00 s, the drone accidentally releases the parcel! The parcel is in "freefall" immediately after it is
released, as defined in Lecture 7. Assume that the magnitude of the acceleration, g = 9.81 m/s?, and that
the drone continues with the same velocity after releasing the parcel. Ignore the effects of air-resistance.
