The average power delivered by the automobile engine can be calculated using the formula P = m*a*v, where m is the mass of the car, a is the acceleration, and v is the final velocity. In this case, the mass is given as 1000 kg and the acceleration can be calculated by dividing the change in velocity (25 m/s) by the time taken (7.50 s), resulting in an acceleration of 3.33 m/s^2. Plugging these values into the formula, we get an average power of 33,300 watts or 33.3 kilowatts. This means that the engine of the sports car is delivering an average of 33.3 kilowatts of power during the acceleration from 0 to 25 m/s. It is important to note that this is an average value and the actual power output of the engine may vary during the acceleration process.
