    Answer:

    4.096 kW

    Explanation:

    Applying,

    P = Fvcos∅…………….. Equation 1

    Where P = Power of the motor, F = Force exerted on the motor, v = Velocity, ∅ = angle.

    From the question,

    Given: F = 500 N, v = 10 m/s, ∅ = 35°

    Substitute these values into equation 1

    P = 500×10×cos35°

    P = 4095.8 W

    P = 4.096 kW

    Hence the power rating of the moto in kW is 4.096 kW
