    Answer:

    Part a)

    Work done by the person is

    W = 5886 J

    Part b)

    power consumed by the person is rate of work done by him

    P = 196.2 W

    Explanation:

    As we know that the mass of climber is 30 kg

    He raised upwards to height 10 m

    Part a)

    Work done against the gravity is given as

    W = mgh

    Now plug in all the values in it

    W = (60 kg)(9.81 m/s^2)(10)

    W = 5886 J

    Part b)

    As we know that power consumed by the person is rate of work done by him

    so here person took 30 s to raise upwards

    so power is given as

    P = \frac{5886}{30}

    P = 196.2 W
