    The weight of the book is, W = 53.9 N

    Explanation:

    The mass of the book, m = 5.5 kg

    The acceleration due to gravity, g = 9.8 m/s²

    The weight of an object is defined as the product of of the mass and acceleration due to gravity,

    W = m x g

    Substituting the given values in the above equation,

    W = 5.5 x 9.8

    = 53.9 N

    Hence, the weight of the book is, W = 53.9 N
