    (a) 5 m/sec

    Explanation:

    we have given r=1 meter

    angular velocity ω = 5 revolution/sec

    we have to find the velocity of turbine blade tip

    the velocity of turbine blade tip is given by v = rω

    where v = velocity of turbine blade tip

    r = radius

    ω = angular velocity

    so v = 5*1 = 5 meter/sec

    so the option (a) will be the correct option as in option (a) velocity is given as 5 meter/sec
