2. While throwing a football, you exert a forward force of 50.0 N on it and push it forward a distance of 1.2 m.

Answer 1

In doing so, you give the football 60 joules of kinetic energy of forward motion.

You did not ask a question but perhaps that is what you want to know.

Not all of the football's kinetic energy is forward motion, (1/2)MV^2. It also spins. The forward force does not impart the spin.
