Answer;
B. A drawn bow is released, causing an arrow to fly across the field.
Explanation;
Potential energy is the energy in a body due to its position. While kinetic energy is the energy in a body due to its motion. The formula for potential energy is mgh, where m stands for mass, g stands for gravitational acceleration and h stands for height.
Potential energy is the stored energy that can become kinetic energy. Kinetic energy is given by 1/2mv², where m is the mass and v is the velocity.
Potential energy = Stored energy, usually energy in bonds, energy in height.
Kinetic energy = Energy of movement
As you draw the bow, the elasticity of the bow stores the energy (potential), and once you release, the arrow flies across the field (kinetic).
