A particle starting from rest travels a distance x in first 2 seconds and a distance y in next two seconds, then

Options

A. y = 4x
B. y=x
C. y = 3x
D. y = 2x

Answer

C

Explanation

Let a be the uniform acceleration of the body. Then
`x =1/2 a(2)^(2) = 2a and x + y =1/2 a(4)^(2) = 4 (2a) = 4x`
`:. y = 4x - x = 3 x `
