A car contains a worn out engine with a power of 32 000 W. The car takes 9.0 s
to accelerate from reat to 15 in/s. A mechanic replaces the engine with a more
powerful but otherwise identical one. The new engine has a power of 62 000 W. Explain how the new engine will affect the time it takes for the car to accelerate from rest to 15m/s
