The initial velocity of a particle is given by u (at t=0) and the acceleration by f,where f=at(a=constant,t=time).Which of the following relation is valid?

A)v=u+at 2 B)v=u+at 2 /2 C)v=u+at D)v=u
Which constant "a" are you talking about?


As it is given as t = 0
Therefore f= 0
we have the relation v= u + at and at= 0
therefore the correct answer is v=u
OPTION D is the right answer 

0 0 0
Hey friend, it is given that u = 0 at t = 0.
Its not given that its t=0 for the whole time
i am correct i guess because the question is very clear
