Question

An airplane has a lot of very closely spaced seats and peanuts and has a mass of 48,420 kg. This tube of aluminum cruises through the skies at 692 km/hr and its roaring engines have a total thrust of 64,148 N. Neglecting all those pesky things like air resistance, altitude, airsickness, fuel burned and ticket prices, how long in seconds does it take this plane to reach cruising speed from rest? (Solve using impulse and momentum)
