Best answer
दिया गया है कि
`F=10" N"," m"=5" kg","u"=0" m"//"s", t=2" s"`.
समीकरण : `F="ma", "s"="ut"+(1)/(2)"at"^(2)" एवं "W="Fs"` से,
त्वरण `a=(F)/(m)=(10" N")/(5" kg")=2" m"//"s"^(2)`.
`:.` तय की गई दूरी `s=(1)/(2)"at"^(2)=(1)/(2)xx2" m"//"s"^(2)xx(2" s")^(2)=4" m"`.
अत: , किया गया कार्य
`W=Fs=10" N"xx4" m"=40" N m"=40" J"`.
