Question

the initial velocity of a particle is u (at t=0) and acceleration f is given by at.which relation is valid:
(a)v=u+at^2
(b)v=u +at^2/2
(c)v=u+at
(d)v=u

Answer 1

initial velocity is u

Answer 2

check the units. (a) and (b) are obviously false.

So, since (d) means constant velocity, (c) is the only possible choice.

Answer 3

V=u at^2

Answer 4

C us correct dear
