    282.6 N

    Explanation:

    Draw a free body diagram of the suitcase. There are three forces:

    Weight force mg pulling down,

    Normal force N pushing up,

    and 100 N down at angle 60° with the horizontal.

    Sum of forces in the y direction:

    ∑F = ma

    N - mg - 100 sin 60° = 0

    N = mg + 100 sin 60°

    N = (20 kg) (9.8 m/s²) + 100 sin 60°

    N = 282.6 N

    Round as needed.
