Question

The force that stops a jet plane as it lands on the flight deck of an aircraft carrier is provided by a series of arresting cables. These cables act like extremely stiff rubber bands, stretching enough to keep from slowing the plane down too suddenly. A Hornet jet with a mass of 13,000 kg lands with an acceleration of -27.6 m/s2 (slowing down). How large is the unbalanced force that the arresting cables exert on the plane?
