    Answer:

    the work done by the motor is 1,044 J.

    Explanation:

    Given;

    the output power of the motor, P = 0.7 hp

    duration of the work, t = 2 s

    The relationship between horse-power and watt is given as;

    1 hp = 745.7 W

    0.7 hp = ?

    0.7 hp = 522 W = 522 J/s

    The work done by the motor is calculated as;

    W = Power x time

    W = 522 J/s  x  2 s

    W = 1,044 J

    Therefore, the work done by the motor is 1,044 J.
