Answer:
[tex]F=125N[/tex]
Explanation: We need to find the average force applied by the player:
[tex]\begin{gathered} m=150g=0.150\operatorname{kg} \\ v=25ms^{-1} \\ t=0.03s \\ v=v_o+at \\ \therefore\Rightarrow \\ 0=v_o+at=25ms^{-1}+a0.03s \\ \therefore\Rightarrow \\ a=-\frac{25ms^{-1}}{0.03s}=-833.333ms^{-2} \\ \therefore\Rightarrow \\ F=ma\rightarrow(0.150)\times(833.333ms^{-2})=-125N \\ \therefore\Rightarrow \\ F=-125N \end{gathered}[/tex]
