Answer:

Step-by-step explanation: We need to find the average force applied by the player:

$\begin{gathered} m=150g=0.150\operatorname{kg} \\ v=25ms^(-1) \\ t=0.03s \\ v=v_o+at \\ \therefore\Rightarrow \\ 0=v_o+at=25ms^(-1)+a0.03s \\ \therefore\Rightarrow \\ a=-(25ms^(-1))/(0.03s)=-833.333ms^(-2) \\ \therefore\Rightarrow \\ F=ma\rightarrow(0.150)*(833.333ms^(-2))=-125N \\ \therefore\Rightarrow \\ F=-125N \end{gathered}$
