The Spanish Armada was commanded by King Phillip II of Spain to attack Britain in 1588. Queen Elizabeth I of England hired Sir Francis Drake to command the Royal Navy, which defeated the Spanish Armada using wind to blow flaming ships into their fleet.
The mechanical energy of an object is equivalent to the sum of its potential and kinetic energy. If the helicopter is grounded, then its mechanical energy will be 20 J. If it is in the air, then its potential energy will be calculated using:P.E = mghAnd then added to the kinetic energy to obtain mechanical energy.
