The answer is 2.3. I just answered this question and got it right.
Can i get brainliest . i think it was used as a way of communication.
a)The ball's potential energy changes as it moves from the release point to the top of the rebound.
b)The ball's potential energy is at its highest and rests when it is in the top position.
<h3>What is potential energy?</h3>
The potential energy is due to the virtue of the position and the height. The unit for the potential energy is the joule.
The potential energy is mainly dependent upon the height of the object.
Potential energy = mgh
The kinetic energy of the body is due to the virtue of motion.
According to the Law of Conservation of Energy, energy can neither be created nor destroyed but can be transferred from one form to another.
The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.
A ball dropped onto a trampoline returns to the same height after the rebound.
Hence, the ball's potential energy changes as it moves from the release point to the top of the rebound. When the ball is at the top position the potential energy is maximum and the ball is at rest.
