Equations of Kinematics

Two bodies $A$ and $B$ start from the same point at the same instant and move along a straight line. Body $A$ moves with uniform acceleration $a$ and body $B$ moves with uniform velocity $v$ . They meet after time $t$ . The value of $t$ is

Show answer and solution

Answer: (a)

They meet when both displacements are equal: $s_A = \frac{1}{2}at^2$ , $s_B = vt$ .
$\frac{1}{2}at^2 = vt \Rightarrow t = \frac{2v}{a}$
So the answer is (a) $\frac{2v}{a}$ .
