Answer: option B.
As the volleyball travels towards the players hands, the ball has a
higher amount of kinetic energy. As the ball hits the players hands the
ball's kinetic energy is transformed into spring/elastic potential
energy as the ball and the player's hands bend for a moment. The ball
then launches from the hands transforming this spring/elastic potential
energy into kinetic energy. As the ball travels up into the air the
kinetic energy of the ball transforms into gravitational potential
energy, because, here, the ball loses velocity and gains height.
Explanation:
1) Kinetic Energy, KE it the energy due to the motion. The higher the speed the higher the KE.
It is evident that as the ball falls toward the player is gains speed and so the KE becomes higher.
Such as the first part of the statment tells: "As the volleyball travels towards the players hands, the ball has a higher amount of kinetic energy"
2) Now, you can compare the contact of the ball with the hands of the player, with a spring or a rubber band, because the hands try to amortiguate the impact, oppose to the initial motion of the ball, and reverse its motion confering new KE.
Such as this part of the statement tells: " As the ball hits the players hands the ball's kinetic energy is transformed into spring/elastic potential energy as the ball and the player's hands bend for a moment. The ball then launches from the hands transforming this spring/elastic potential energy into kinetic energy".
3) Then, the ball starts to gain altitude, which is gravitational potential energy, at expense of losing speed, which is KE.
Such as, this part of the statement tells: "As the ball travels up into the air the kinetic energy of the ball transforms into gravitational potential energy, because, here, the ball loses velocity and gains height."
