A 15000-kg helicopter is lowering a 4800-kg truck by a cable of fixed length. The truck, helicopter, and cable are descending at 16.0 m/s and must be slowed to 5.00 m/s in the next 53.0 m of descent to prevent damaging the truck. Assume a constant rate of slowing.

(a) Determine the tension in the cable.

kN

(b) Determine the lift force of the helicopter blades.

kN
