A body falling from rest describes distances s1, s2, s3 in the first, ...
Solution:

To solve the problem, we need to use the formula for the distance traveled by a body under free fall, which is:

s = (1/2)gt^2

where s is the distance, g is the acceleration due to gravity, and t is time.

Let us assume that the body falls through a height h. Then, we have:

s1 = (1/2)gh
s2 = (1/2)g(2)^2 = 2gh
s3 = (1/2)g(3)^2 = 4.5gh

Now, we need to find the ratio of s1:s2:s3. Dividing s1, s2, and s3 by h, we get:

s1/h = 0.5
s2/h = 2
s3/h = 4.5

Hence, the ratio of s1:s2:s3 is 0.5:2:4.5, which simplifies to 1:4:9. Therefore, the answer is option (d).

Summary:
- We used the formula for the distance traveled by a body under free fall.
- We assumed that the body falls through a height h.
- We calculated s1, s2, and s3 in terms of h.
- We divided s1, s2, and s3 by h to get the ratio.
- The ratio simplifies to 1:4:9, which is option (d).

A body falling from rest describes distances s1, s2, s3 in the first, ...
S=it+1/2gt^2.here,S is directly proportional to t^2.S1:S2:S3=t1^2:t2^2:t3^2.=1^2: 2^2: 3^2 = 1:4:9.
