Fnet(t)=mv2-mv1 is totally wrong, you can't get a force by subtracting two momenta.
You get the acceleration on each from a = ∆V/∆t
and from the acceleration and the mass, you get the force from F = ma
player 1, ∆V = 8±1.77 (– if direction is unchanged, + if the direction is reversed)
∆t = 0.3 sec
player 2, ∆V = 12±1.77 (– if direction is unchanged, + if the direction is reversed)
∆t = 0.3 sec
you have the masses, so you have all you need to do the calculation.

e)1/2 mv^2 =F*d
= F= mv^2/2d
1/2*100*(5)^2 = 1250 J = 1.25 kJ
