1.

A body starts from rest and moves with constant acceleration for t s. It travels a distance x_(1) in first half of time and x_(2) in next half of time, then

Answer»

`x_(2) = x_(1)`
`x_(2) = 2x_(1)`
`x_(2) = 3x_(1)`
`x_(2) = 4x_(1)`

SOLUTION :`a = (x_(2) - x_(1))/(t^(2))` …..(1)
`x_(1) = (1)/(2) a t^(2)`
from eqn (1) `RARR a t^(2) = x_(2) - (1)/(2) a t^(2)`
`a t^(2) + (1)/(2) a t^(2) = x_(2)`
`(3)/(2)a t^(2) = x_(2)`
`3x_(1) = x_(2)`
