Week 10: Aircraft Carrier. Paper Airplanes. Solving for acceleration.
Our age is before all things a practical one. It demands of us all clear and tangible results of our work. – Theodor Svedberg
You’re going to solve just 1 problem:
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?
*You MUST include a free-body diagram with the solution
