    Answer:

    Explanation:

    In calm water there is no acceleration so reading

    R = mg = 183

    m = 183 / 32

    At maximum upward acceleration reading

    R₁  = mg + ma

    = 183 + (183 / 32 ) x a

    230 = 183 + (183 / 32 ) x a

    a = 8.22 ft /s²

    B )

    In case of downward acceleration , reading

    R₂ = mg – ma

    138 = 183 – (183/32) a

    a = 7.87 m /s²
