Question

The distance moved by a freely falling body (starting from rest) during ` st, 2nd, 3rd,……nth` second of its motion are proportional to .
A. `(n-1)`
B. `(2n-1)`
C. `(n^(2)-1)`
D. `(2n-1)//n^(2)`

Answer 1

Correct Answer - B
`S_(n)=g(n-(1)/(2))`, ratio `=(g)/(2):(3g)/(2):(5g)/(2)` …. `(2n-1)(g)/(2)`
`S_(n)prop(2n-1)`
