Audio Guided Solution The takeoff speed of a military aircraft
from an aircraft carrier is approximately 170 mi/hr relative to
the air. They acquire this speed through a combination of a
catapult system present on the aircraft carrier and the
aircraft's jet propulsion system. A common strategy is to head
the carrier and the plane into the wind. If a plane is taking
off from an aircraft carrier which is moving at 40 mi/hr into a
20 mi/hr headwind, then what speed relative to the deck of the
aircraft carrier must it obtain to takeoff? Audio Guided

Effective Problem Solver - Read the problem carefully and
develop a mental picture of the physical situation. If
necessary, sketch a simple diagram of the physical situation to
help you visualize it. - Identify the known and unknown
quantities in an organized manner. Equate given values to the
symbols used to represent the corresponding quantity - e.g.,
