A. the medium
For refraction to occur, there has to be change from one medium to another. For example rays of light would refract as the travel from air to water.
Use pythagorean's theorem for this, with 7 as a and 5 as b. pythagorean's theorem says that a^2 + b^2 = c^2, so 7^2 * 5^2 = c^2. this gives you 49 + 25 = c^2, so 74 = c^2. c = sqrt 74, which is approximately 8.60 km
It would be kinetic and potential energy, potential from the force of the kick, and kinetic from energy exerted.
