Answer:-600N

Step-by-step explanation:

Mass(m)=1000kg

Initial velocity(u)=25m/s

Final velocity(v)=12.5m/s

Time(t)=22 seconds

v=u+axt

12.5=25+ax22

collect like terms

12.5-25=22a

-12.5=22a

Divide both sides by 22

-12.5/22=22a/22

-0.6=a

Acceleration=-0.6

Force=mass x acceleration

Force=1000 x -0.6

Force=-600
