The launching catapult of the aircraft carrier gives the jet fighter a constant acceleration of 59 m/s2 from rest relative to the flight deck and launches the aircraft in a distance of 80 m measured along the angled takeoff ramp. If the carrier is moving at a steady 31 knots (1 knot = 1.852 km/h), determine the magnitude v of the actual velocity of the fighter when it is launched. Assume = 13°.

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.
