Answer 1

$\boxed {\underline {\mathbb {FINAL\:ANSWER:-}}}$

$\:initial\: velocity=60kgm/s\\\:final\:velocity=80kgm/s\\\:change\:of\:momentum=2kgm/s\\change \:in\:momentum\:of\:body\:=20kgm/s\\force\:applied\:=5N\\Impilse=20Ns\\impulse\:experience\:by\:the\:body\:equals\:to\:change\:\:in\:momentum\:\:of\:body$

$\boxed {\underline {\mathbb {GIVEN:-}}}$

$m=10kg\\u=6m/s\\v=8m/s\\t=4s$

$\boxed {\underline { \mathbb {TO \:FIND:-}}}$
