There are many forms of energy, but they can all be put into two categories: kinetic and potential. Kinetic energy is motion––of waves, electrons, atoms, molecules, substances, and objects. Potential energy is stored energy and the energy of position––gravitational energy
The answer is D because theres nothing stopping that person from falling
Answer:
Bone homeostasis involves multiple but coordinated cellular and molecular events. Two main types of cells are responsible for bone metabolism: osteoblasts (which secrete new bone), and osteoclasts (which break bone down).
Explanation:
Ek = 1/2 mv^2
If they are travelling at the same speed the one with the larger mass will have more kinetic energy as kinetic energy and mass are proportional.
Since the ball is fired horizontally, the initial y velocity is zero and the time to hit the ground is the same as if the ball was simply dropped from the cliff. So you can solve the y position function:

giving a height of 44.1m.
The given final velocity vector tells us that the initial x-directed velocity was about 17m/s.
