If displacement x= t^(4) , then the ratio of acceleration and velocity of motion will be

Answer»

`(3)/(t)`
`(t)/(3)`
3t
`(4)/(t)`

SOLUTION :`x = t^(4)`
`:. ` VELOCITY = `(DX)/(DT) = 4t^(3)`, Acceleration = `(d^(2))/(dt^(2))=12t^(2)`
`:. ("Acceleration ")/("Velocity ") = (12t^(2))/(4t^(3)) = (3)/(t)`
