The distances covered by a freely falling body in its first, second, third, ……, n th seconds of its motion
Text Solution
Verified by ExpertsThe correct answer is:
A
Distance travelled by a body in nth second is 
Here, u = 0, a = g
Distance travelled by the body in 1 st seconds is 
Distance travelled by the body in 2 nd seconds is

Distances travelled by the body in 3 rd seconds is

and so on.
Hence, the distances covered by a freely fallings body in its first, second, third …..nth second of its motions forms an arithmetic progression.
