    Ok, so you've got to figure out a force F and you have the speed in which the boxer punches on determinate time and the mass of the sheet of paper.

    So based on the formula that says that the Force is equal to the mass multiplied by the acceleration = > F=ma.

    You look at it and see that you only have mass which is measured on KG so there is no problem.

    then you have the acceleration which is measured on meters and is defined by: a = Δv/Δt

    So now you can replace the velocity and the time you have there

    ⇒ a 25m/s / 0.05s

    you have computing that ⇒ 50m because the seconds were cancelled out.

    and then you plug the meters into the force equation.

    F = (0.005kg) (50)

    F=0.25N

    so the boxer will have a force of 0.25 Newton's.
