Burning of wood is the only combustion reaction we have listed among the options.
Combustion is an exothermic reaction in that heat is released to the environment. Combustion usually occurs in the presence of oxygen. In this reaction, a fuel source, the wood reacts with oxygen to produce heat energy and some other products.
The total mechanical energy of the ball is the sum of its potential energy U and its kinetic energy K, therefore: so, the total mechanical energy of the basketball is 118 J.
