You are on an airplane that is landing. The plane in front of your plane blows a tire. The pilot of your plane is advised to abort the landing, so he pulls up, moving in a semicircular upward-bending path. The path has a radius of 500 m with a radial acceleration of 18 m/s2. What is the plane's speed?

    Answer: plane speed is 94.87m/s

    Explanation: since the plane move upward in a semicircular path, the acceleration is a centripetal acceleration with radius of 500metre. But the Centripetal acceleration is given as

    Centripetal acceleration

    = Speed ²/radius

    Making speed subject of formula we have,

    Speed² = centripetal acceleration*radius

    Speed² = 18*500

    =9000

    Speed = √9000

    = 94.87m/s
