    Answer:

    9780 W

    Explanation:

    Power: This can be defined as the rate at which work is done. The S.I unit of power is Watt (W).

    From the question,

    P = W/t………………….. Equation 1

    Where P = power, W = work, t = time.

    But,

    W = F×d………….. Equation 2

    Where F = force, d = distance.

    Substitute equation 2 into equation 1

    P = (F×d)/t…………….. Equation 3

    Given: F = 24450 N, d = 12 m, t = 30 s.

    Substitute these vales into equation 3

    P = (24450×12)/30

    P = 9780 W.

    Hence the power needed for the elevator trip = 9780 W

    Answer:

    9,780Watts

    Explanation:

    Power is defined as the rate of workdone with respect to time.

    The formula for calculating power P needed by the eleveator is expressed as;

    Power = \frac{workdone}{time}

    Since Workdone = Force*distance then;

    Power = \frac{force * distance}{time}

    Given the weight of elevator = 24,450Newtons

    distance moved by the elevator = 12m

    time taken = 12seconds.

    Substituting this values in the formula given will give;

    Power = \frac{24,450*12}{30} \\Power = \frac{293,400}{30} \\Power = 9,780Watts\ or\ 9.78kW

    The amount of power needed for the elevator trip is 9,780Watts
