A melon is projected into the air with 100 J of kinetic energy in the presence of air resistance. When it returns to its initial level its kinetic energy is

Question

Quizplus · Accepted Answer

When a melon is projected into the air with kinetic energy and there is air resistance present, some of the kinetic energy is converted into other forms of energy (like heat) due to the work done against air resistance. Therefore, when the melon returns to its initial level, its kinetic energy will be less than the initial 100 J.
