    Answer:

    5000 W

    Explanation:

    Applying,

    P = W/t…………….. Equation 1

    Where P = Power, W = work done by the car, 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

    From the question,

    Given: F = 2000 N, d = 50 m, t = 20 seconds.

    Substitute these values into equation 3

    P = (2000×50)/20

    P = 5000 W
