In straight-line motion with constant acceleration, which equation correctly relates final velocity $v$, initial velocity $u$, acceleration $a$, and time $t$?
A$v=u+at$
B$v=u-at^2$
C$v^2=u^2+at$
D$s=ut+a$
Answer & Solution
Correct answer: A. $v=u+at$
For uniformly accelerated motion, the standard first equation is $v=u+at$. The other options are dimensionally or conceptually incorrect forms of the kinematic equations.
