The Eurostar provides international high speed train service between Paris, London, and Brussels through the English Channel Tunnel. Eurostar trainsets can operate at maximum speeds of 3.00 × 10² km/h. Assume that the resistance between the train and the track is 115 × 10³ newtons. If air resistance adds an additional 25.5 × 10³ newtons, determine the horsepower needed to power the engine at maximum speed. [Note: Power = (force) × (velocity)]
