Kendra loves rolling down hills. She finds a steep hill to roll down. As she is rolling, when is her kinetic energy most likely the highest?

Answer 1

Kinetic energy is the energy of motion and is given by the formula \( KE = \frac{1}{2}mv^2 \), where \( m \) is the mass and \( v \) is the velocity of the object. As Kendra rolls down the hill, her potential energy (due to her height) converts into kinetic energy.

Kendra's kinetic energy is most likely the highest at the bottom of the hill. At this point, she has converted most of her potential energy into kinetic energy as she reaches her maximum speed. As she rolls down, her height decreases and her speed generally increases, leading to a higher kinetic energy. Therefore, the moment just before she comes to a stop at the bottom of the hill is when her kinetic energy is at its highest.
