A body experiences acceleration for 6 seconds after starting from rest. If it travels a distance x_1 in first 2 s, x_2 in the next two s, and x_3 in the last two s. then :

Answer»

`x_1 : x_2 : x_3 : =1:1:1`
`x_1 : x_2 : x_3 : =1:2:3`
`x_1 : x_2 : x_3 : =1:3:5`
`x_1 : x_2 : x_3 : =1:4:8`

SOLUTION :`x_1=ut+(1)/(2)at^(2) implies x_1(1)/(2)a.(2)^(2)`
`impliesx_1 =2a`
`x_1+x_2=(1)/(2)a(4)^(2)implies x_2+x_1=8a`
`x_1+x_2+x_3=(1)/(2)a(6)^(2)=18a`
