thank you, but could you explain it using steps? I kinda wanna know how exactly it is done. if u would, it would be great!

Momentum=mass × velocity so... change in momentum= mass ×change in velocity
=> change in momentum= 3(40-10)=3×30=90kg m/s
so the change in momentum is 90kg m/s _________________ initial momentum=3×40=120 finalmomentum=3×10=30 (final momentum) / ( initial momentum ). = 30/120 =1/4 => final momentum = 1/4 times initial momentum

(final momentum) / ( initial momentum ).
= 30/120
=1/4
=> final momentum = 1/4 times initial momentum
hope it helps you..
