## Question:

A jet plane having a mass M takes off from an aircraft carrier such that the engine thrust varies as shown by the graph. If the carrier is traveling forward with a speed v, determine the plane’s airspeed after time t. Units Used: Mg = ${ 10 }^{ 3 }$ kg , kN = ${ 10 }^{ 3 }$ N Given: M = 7 Mg , ${ t }_{ 1 }$ = 2 s , v = 40 km/hr , ${ t }_{ 2 }$ = 5 s , ${ F }_{ 1 }$ = 5 kN , t = 5 s , ${ F }_{ 2 }$ = 15 kN
