Nico Gallegos · Answer 1

Answer: the energy is being transferred from his arm muscles to the ball.

Explanation:

1) Initially the ball has zero kinetic energy as it is at rest, and zero potential energy (it is at a lowest level).

2) By doing work on the ball, Abin changes the mechanical energy of the ball. The ball will start to move (kinetic energy) and will reach a higher position (potential energy).

3) The energy was transferred by Abin's arm muscles, which used the chemical energy stored in its cells.

Aliyah · Answer 2

The correct answer is that the energy is being transferred from Abin’s arm muscles to the ball when he lifts the ball up. The kinetic energy is involved in moving the ball and would be recorded in units of Joules.
