velocity

Let an object of mass 'm' be travelling along a path of Initial velocity 'u=0' and Final velocity 'V' and distance 's' . Let a be acceleration where a = v-u/t , v is the Final velocity , u is the Initial velocity and t is time .We know ,

F=ma

F= m(v-u)/t

F= m(v-0)/t where u=0 given in the condition

F= mv/t

w/s= mv/t where F=w/s

w/s= m(s/t)/t where v =s/t

w/s=ms/t2

wt²=ms²

w=ms2/t2

w=ms2/t2

w=m(s/t)²

w=mv²
