Equations of Kinematics

Two bodies ' $A$ ' and ' $B$ ' start from the same point at the same instant and move along a straight line. 'A' moves with uniform acceleration (a) and '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) $\frac{2V}{a}$ .
