    Answer:

    6779.7m/s

    Explanation:

    Using

    GMm/(Re +h)² = mv²/ (Re+h)

    So making v subject we have

    V= √GM/Re+h

    So

    V = √ 6.67*10^-11 x 5.97*10^24/(6371+2300)*10^3

    V= 6779.7m/s

    Note h = height of satellite

    Re= radius of the earth

    M = mass of the earth
