A particle starting from rest falls from a certain height. Assuming that the value of acceleration due to gravity remains the same throughout motion, its displacement in three successive half second intervals are 𝑆1 , 𝑆2, 𝑆3. Then,

Question : A particle starting from rest falls from a certain height. Assuming that the value of acceleration due to gravity remains the same throughout motion, its displacement in three successive half second intervals are 𝑆1 , 𝑆2, 𝑆3. Then,

(A) 𝑆1: 𝑆2: 𝑆3: 1: 5: 9

(B) 𝑆1: 𝑆2: 𝑆3: 1: 2: 3

(C) 𝑆1: 𝑆2: 𝑆3: 1: 1: 1

(D) 𝑆1: 𝑆2: 𝑆3: 1: 3: 5

Answer : option (D)

Solution :

A particle starting from rest falls from a certain height. Assuming that the value of acceleration due to gravity remains the same throughout motion, its displacement in three successive half second intervals are 𝑆1 , 𝑆2, 𝑆3. Then,
