A body moves with uniform acceleration. If v_(1), v_(2) and v_(3) be the average velocities in three successive intervals of time t_(1), t_(2) and t_(3), then :

Answer»

`v_(1)-v_(2) :v_(2)-v_(3)=t_(1)-t_(2):t_(2)+t_(3)`
`v_(1)-v_(2) :v_(2)-v_(3)=t_(1)+t_(2):t_(2)+t_(3)`
`v_(1)-v_(2) :v_(2)-v_(3)=t_(1)+t_(2):t_(1)-t_(3)`
`v_(1)-v_(2) :v_(2)-v_(3)=t_(1)+t_(2):t_(2)-t_(3)`
