MCQ

Two bodies $A$ and $B$ start from rest from the same point with a uniform acceleration of $2\,m / s ^2$. If $B$ starts one second later, then the two bodies are separated, at the end of the next second, by $.............\,m$

A
$1$
B
$2$
✓
$3$
D
$4$

✓

Answer

Correct option: C.

$3$

c
(c)

$s_B=\frac{1}{2} \times 2 \times(1)^2=1\,m$

$s_A=\frac{1}{2} \times 2 \times(2)^2=4\,m$

$s_A-s_B=3\,m$
