Answer» Answer: The answer is 4000 W. Explanation: As the car is going up an INCLINE with a slope of 2 in 25 at a steady speed of 18kmph. Therefore the slope is tan(θ) = 2/25 = sin(θ) approximately. Thus the force "F" = 1000 X 10 x 2/25 And power = FV = 10000 x 2/25 x 18 x 5/18 = 4000 W Thus the power of ENGINE is 4000 W. |
