Which of the following are possible? A ) it is possible to have only potential energy B none are possible B C ) D it is possible to have both types of energy it is possible to have only kinetic energy

The correct answer is D) it is possible to have both types of energy.<br /><br />Explanation:<br />Potential energy and kinetic energy are two forms of mechanical energy. Potential energy is the energy an object possesses due to its position or configuration, while kinetic energy is the energy an object possesses due to its motion.<br /><br />It is possible to have both types of energy at the same time. For example, when an object is at a certain height above the ground, it has potential energy due to its position. If the object is then released and starts moving, it will have kinetic energy due to its motion. In this case, the object has both potential energy and kinetic energy.<br /><br />Therefore, option D) it is possible to have both types of energy is the correct answer.
