Question
Here is the question:
A helicopter flies to the right (in the +x direction) at a constant speed of 11 m/s, parallel to the surface of the ocean. A 1150 kg package of supplies is suspended below the helicopter by a cable as shown in the figure: the package is also traveling to the right in a straight line, at a constant speed of 11 m/s. Choose the package as the system. What is the rate of change of the momentum of the system? kg m/s/s List all the objects that are exerting forces on the package. (Note that "gravity" is not an object.) helicopter Earth cable air Represent the package as a dot. Draw a careful force diagram ("free-body diagram") showing all the forces acting on the package. You should have the same number of arrows as you had objects in your list in part (b), and the tail of each arrow should be on the package. Label each force with the name of the object exerting the force. What is the magnitude of the tension in the cable supporting the package? Carefully show all steps in your work. Write the force exerted on the package by the cable as a vector. What is the magnitude of the force exerted by the air on the package? Write the force on the package by the air as a vector. The pilot is concerned about whether or not the cable, whose breaking strength is listed at 11800 N, is strong enough to support this package under these circumstances. Will the cable break? no yes
