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.

The correct answer is A) coal deposits.
During the Late Carboniferous, Indiana lay close to the equator, making the climate humid and warm. Swamps and wetlands were prominent in much of the state. Dominant fossil plants from this time include lycopods, conifers, and seed ferns (extinct gymnosperms). Plant material accumulated in these areas of Indiana and eventually became the source of Indiana’s abundant coal deposits.
During this time, rivers drained the remnants of the Acadian mountain. Large amounts of sand stayed on the banks of the rivers. Scientists and archeologists working in the zone have found fossils of bryozoans, crinoids, gastropods, and brachiopods. There many carboniferous rocks in the southwestern territories of Indiana.
