The kinetic energy, in joules, of an object with mass kilograms traveling at a speed of meters per second is given by the function , where . Which of the following is the best interpretation of in this context?
Explanation
Choice A is correct. It's given that the kinetic energy, in joules, of an object with a mass of kilograms traveling at a speed of meters per second is given by the function , where . It follows that in the equation , is the value of , or the speed of the object, in meters per second, and is the kinetic energy, in joules, of the object at that speed. Therefore, the best interpretation of in this context is the object traveling at meters per second has a kinetic energy of joules.
Choice B is incorrect. The object traveling at meters per second has a kinetic energy of joules.
Choice C is incorrect. The object traveling at meters per second has a kinetic energy of joules.
Choice D is incorrect. The object traveling at meters per second has a kinetic energy of joules.
