Answer 2

$\bold\red{\underline{\underline{Answer:}}}$

$\bold{Force \ is \ 125 \ N}$

$\bold\orange{Given:}$

$\bold{Mass(m)=25 kg}$

$\bold{Initial \ velocity (u)= 10 \ m \ s^{-1}}$

$\bold{Final \ velocity (v)=20 \ m \ s^{-1}}$

$\bold{Time(t)=2 \ s}$

$\bold\pink{To \ find:}$

$\bold{Force(F) \ of \ an \ object.}$

$\bold\blue{Explanation}$

$\bold{=>Force=mass×acceleration}$

$\bold{According \ to \ Newton's \ first}$

$\bold{equation \ of \ motion}$

$\bold{=>v=u+at}$

$\bold\green{\underline{\underline{Solution}}}$

$\bold{According \ to \ Newton's \ first}$

$\bold{equation \ of \ motion}$

$\bold{=>v=u+at}$

$\bold{=>20=10+a(2)}$

$\bold{=>a=\frac{10}{2}}$

$\bold{=>a=5 \ m \ s^{-2}}$

_________________________________

$\bold{Now \ force,}$

$\bold{=>F=m×a}$

$\bold{=>F=25×5}$

$\bold{=>F=125 \ N}$

$\bold{Therefore,}$

$\bold\purple{Force \ is \ 125 \ N}$
