Neither of the above but a constant value that is independent of the initial velocity

The value of the ratio will depend on the value of the initial velocity and will change for each case.

Q. If I drop a ball near the surface of the moon, will it still cover distances in the ratio 1:4:9 every second of its fall?

If I dropped a ball near the surface of the moon, will it still fall in such a way that the ratio of thetotal distances it covers as it falls , after every second, is in the ratio 1:4:9 ?

In a race Karan covers 1m in $1^{s t}$ second, in the next second he covers twice the distance he covered in $1^{s t}$ second, in $3^{r d}$ second he covers twice the distance which covered in $2^{n d}$ second and he continues to run like this till six seconds. After that due to tiredness his speed keeps on going down, as in $7^{t h}$ second he covers only half the distance which he covered in $6^{t h}$ second and in $8^{t h}$ second he covers half the distance which he covered in $7^{t h}$ second and he continuous in that manner. If Karan completes the race in 9 seconds, find the length of given track. [4 MARKS]
