A Boeing 747—a small, short-range jet with a mass of 250,000 kg—sits at rest at the start of a runway. The pilot turns the pair of jet engines to full throttle, and the thrust accelerates the plane down the runway. After traveling 1240 m, the plane reaches its takeoff speed of 90 m/s and leaves the ground. What is the thrust of each engine? 67 kN 133 kN 320 kN 410 kN 532 kN

A fully loaded Boeing $777-200$ jet transport aircraft weighs 325,000 kg. The pilot brings the 2 engines to full takeoff thrust of $450 \mathrm{kN}$ cach before releasing the brakes. Neglecting aerodynamic and rolling resistance, estimate the minimum runway length and time needed to reach a takeoff speed of 225 kph. Assume engine thrust remains constant during ground roll.
Boeing 767-400ER model airplane has two engines. Each engine can have a maximum thrust (mechanical force) output of 270 kN. When the plane is cruising at 713.88 km/h, the pilot decides to increase the speed to the typical 850.0 km/h. If drag on the plane is on average 28559 N, and the engines are engaged at 40.79 % of their maximum thrust output, and the plane weighs 171041 kg, how long does it take to reach the new cruising speed?

An Airbus A320 jetliner has a takeoff mass of 75,000 kg. It reaches its takeoff speed of $82 \mathrm{m} / \mathrm{s}(180 \mathrm{mph})$ in $35 \mathrm{s}$. What is the thrust of the engines? You can neglect air resistance but not rolling friction.
