Question

A particle starting from rest falls from a certain height.
Assuming that the acceleration due to gravity remain the
same throughout the motion, its displacements in three
successive half second intervals are S₁, S₂ and S₃ then
(a) S₁ : S₂ : S₃ = 1 : 5 : 9 (b) S₁ : S₂ : S₃ = 1 : 3 : 5
(c) S₁ : S₂ : S₃ = 9 : 2 : 3 (d) S₁ : S₂ : S₃ = 1 : 1 : 1

Answer 1

Answer:

The correct options is A

a). S¹: S²: S³ = 1 : 5 : 9

Answer 2

Answer:

option b is correct. s1 s2 se = 1 3 5
