B) gravitational to kinetic
Explanation:
The skydiver, when he is located at a certain height h above the ground, possesses gravitational potential energy, equal to:
[tex]U=mgh[/tex]
where m is the mass of the skydiver, g is the gravitational acceleration and h is the height above the ground. As he falls, its height h decreases, while his speed v increases, so part of the gravitational potential energy is converted into kinetic energy, which is given by
[tex]K=\frac{1}{2}mv^2[/tex]
so, we see that as v increases, the kinetic energy increases. Therefore the correct answer is
B) gravitational to kinetic
