    Answer:

    the work done by the lawnmower is 236.14 J.

    Explanation:

    Given;

    power exerted by the lawnmower engine, P = 19 hp

    time in which the power was exerted, t = 1 minute = 60 s.

    1 hp = 745.7 watts

    The work done by the lawnmower is calculated as follows;

    Work = Energy = \frac{Power}{time} \\\\Work = \frac{(19 \times 745.7)}{60} = 236.14 \ J

    Therefore, the work done by the lawnmower is 236.14 J.
