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 :
