A helicopter holding a 70 kilogram package suspended from a rope 5.0 meters long accelerates upward at a rate of 5.2 m/s
^{2}
. Neglect air resistance on the package.
(a) On the diagram below, draw and label all of the forces acting on the package.
(b) Determine the tension in the rope.
(c) When the upward velocity of the helicopter is 30 meters per second, the rope is cut and the helicopter continues to accelerate upward at 5.2 m/s
^{2}
. Determine the distance between the helicopter and the package 2.0 seconds after the rope is cut.
