    Answer: 1925 joules

    Explanation:

    weight of man = 550 N

    height climbed = 3.5m

    Work = ?

    Since, work is done when the man pulled his weight over the height; work is expressed as the product of weight and height climbed

    i. e Workdone = 550N x 3.5m

    = 1925 joules

    Thus, the man did a work of 1925 joules while climbing
