1 Answer

Answer :

I’ll give you some hints: The mass of the helicopter is irrelevant to the solution. All you needs is the mass of the load (the car) and the acceleration to solve the problem. Remember that the helicopter is the motive power and the cable is attached below it. Tension is directly related to force. Now go find the equations in the text, plug and crank.
