A two-engine jet transport has a loaded weight of 94000 Ib and a forward thrust of 8770 Ib per engine during takeoff. If the transport requires 6020 ft of level runway starting from rest to become airborne at a speed of 145 knots (1 knot = 1.151 mi/hr), determine the average resistance R to motion over the runway length due to drag (air resistance) and mechanical retardation by the landing gear. Answer R = i Ib

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

A 10.1-Mg truck is resting on the deck of a barge which displaces 209 Mg and is at rest in still water. If the truck starts and drives toward the bow at a speed relative to the barge Vrel = 7.8 km/h, calculate the speed v of the barge. The resistance to the motion of the barge through the water is negligible at low speeds. 209 Mg Answer: v= i 7.8 km/h 10.1 Mg km/h
