The force T exerted by the engine in an aircraft is 20000N. Calculate the work done by the engine while the aircraft travels a distance of 500km?

10000000000J

To calculate the work done by the engine, we need to use the formula: Work = Force x Distance Given: Force (T) = 20000 N Distance = 500 km However, we need to convert the distance from kilometers to meters because the force is given in Newtons, which is the SI unit of force, and the formula requires the distance to be in meters. 1 kilometer = 1000 meters So, the distance in meters is: Distance = 500 km × 1000 m/km = 500000 meters Now we can calculate the work done: Work = Force x Distance Work = 20000 N × 500000 m Work = 10,000,000,000 N·m Therefore, the work done by the engine while the aircraft travels a distance of 500 km is 10,000,000,000 N·m (Newton-meters), also known as joules (J).
