Avolleyball player is setting the ball by hitting it directly up with her hands. describe the energy transformations in the volleyball play. which of the following statements uses the following terms correctly: spring/elastic potential energy, kinetic energy, and gravitational potential energy. a. as the volleyball travels towards the players hands, the ball has a higher amount of spring/elastic potential. as the ball hits the players hands the ball's kinetic energy is transformed into gravitational potential energy as the ball and the player's hands bend for a moment. the ball then launches from the hands transforming this gravitational 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. 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. c. 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 height and gains velocity.

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."

Answer

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

explanation

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
