Answer:

99kg m/s

Explanation:

[tex]p=m\Delta v \\\\\Delta v=20-0.20=19.8m/s \\\\p=5(19.8)=99[/tex]

Hope this helps!

Answer:

99 kg m/s

Solution,

Initial speed(u)=20 m/s

final speed(v)=0.20 m/s

change in momentum∆P=m(v-u)

∆P=5(0.20-20)

∆P=5*19.8

∆P=99 kg m/s

Momentum of the body is decreased by 99 kg m/s

hope this helps...

Good luck on your assignment...
