Answer:
f = ma
f = m (v-u)÷ t ( cross multipilcation)
f= 0
ft = m( v- u )
0 = m( v-u)
0= mv - mu ( inter change 0 and mu )
mu= mv ( cutting of m)
u=v
hence proved

AnswerNewton second law states that the rate of change of momentum is directly proportional to netforce acting on a body.
so, Fnet=m(v-u)/t
F=ma
by this we can say the body is same state until external force acts on it so body is in state until net force (Fnet) act on it:
