For motion with constant acceleration, which equation directly relates final velocity $v$, initial velocity $v_0$, acceleration $a$, and elapsed time $t$?
A$v=v_0+at$
B$x=x_0+vt$
C$v^2=v_0^2+at$
D$x=x_0+\dfrac{1}{2}at$
Answer & Solution
Correct answer: A. $v=v_0+at$
The first kinematic equation for constant acceleration is $v=v_0+at$. The other options are incomplete or incorrect forms of standard equations.
