Jose is using a swing at the playground. At which point in a swing does he have the highest kinetic energy?

swinging upward

the top of the swing

swinging downward

the bottom of the swing

The highest point where Jose would have the highest kinetic energy would be at the bottom of the swing. This is because at the bottom of the swing, his velocity is at its highest and therefore his kinetic energy is also at its highest.
