Question P4.4 The Boeing 787 Dreamliner twin-engine aircraft in level flight covers 1.0 km in 4 seconds. If the thrust from each of its engines is 228 KN, determine; (a) the work done during the distance covered (b) the power used Task M2 Determine the retarding force on a freely falling body when it impacts upon a stationary object and is brought to rest without rebound, in a given distance (M2) Question M2.1 The hammer of a pile driver of mass 2.4 tonne falls a distance of 3.3 m onto a pile. The impact takes place in 26 milliseconds and the hammer does not rebound. Determine the average applied force exerted on the pile by the hammer Question P4.4 The Boeing 787 Dreamliner twin-engine aircraft in level flight covers 1.0 km in 4 seconds.
