MCQ
A body starts to fall freely under gravity. The distances covered by it in first, second and third second are in ratio
  • $1:3:5$
  • B
    $1:2:3$
  • C
    $1:4:9$
  • D
    $1:5:6$

Answer

Correct option: A.
$1:3:5$
a
(a) ${S_n} = u + \frac{g}{2}(2n - 1)$; when $u = 0$,

${S_1}:{S_2}:{S_3} = 1:3:5$
