5. If you were asked to give an example of kinetic and potential energy, which of the following would be the best choice.
A. An example of kinetic energy is Dwayne Wade scoring a layup at a Heat game while an
archer pulling the string all the way back on a bow and arrow is an example of potential
energy
B. An example of kinetic energy is a roller coaster at its fastest speed but the roller coaster
at its slowest speed is an example of potential energy.
C. An example of kinetic energy is a ball rolling in the street and a baby crawling is an
example of potential energy.
D. An example of kinetic energy is airplane flying in the sky while running water is an
example of potential energy.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
