Homework Help: Physics Homework Help - Force when kicking a ball

    Physics Homework Help -- Force when kicking a ball

    1. The problem statement, all variables and given/known data
    I have a few physics problems on my homework, I need help.

    A player kicks a 0.5kg ball with a force of 50N, what is the force on his foot?

    2. Relevant equations
    F = Mass * Acceleration

    3. The attempt at a solution
    I was thinking either 50N or 25N would be the solution because when I think of it logically, a 1kg ball would hit my foot harder, but also that could be because force of friction.. If there was no friction on the ground.. it would be 50N right?

    Have you learnt newtons third law?
    It says that every reaction has an equal and opposite reaction.

    So i have given you enough clue.You can now calculate easily the answer.:cool:
