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
