Cats Chasing a Mouse: Understanding Kinetic Energy

What is true about the kinetic energy of elf just before she catches the mouse?

A. the kinetic energy of elf is greater than that of yoda

B. The kinetic energy of elf is smaller than that of yoda

C. The kinetic energy of both are equal

D. The elf has no kinetic energy

Final answer:

Elf, the cat, has greater kinetic energy just before capturing the mouse because her increased speed leads to a higher kinetic energy, based on the formula KE = ½mv².

The question you're asking is about kinetic energy, which is a concept in Physics. Kinetic energy (KE) is the energy an object has due to its motion, which can be calculated using the formula KE = ½mv², where 'm' is mass and 'v' is velocity. Since Yoda and Elf weigh the same and Elf ran faster to catch the mouse, Elf would have a higher kinetic energy just before catching the mouse due to her higher velocity. This is because kinetic energy is proportional to the square of the velocity, so even a small increase in speed results in a significantly larger increase in kinetic energy.
