A body is moved along a straight line by a machine delivering constant power, the distance moved by the body in time in proportional to :

Answer»

`t^(3//2)`
`t^(3//4)`
`t^(2)`
`t^(1//2)`

Solution :SINCE POWER is constant .
`:. ML^(2)T^(-3)`= constant
As M is constant
`:. L^(2)T^(-3)const. implies L^(2) propT^(3) LpropT^(3//2)`
or distance `PROP` `("time")^(3//2)`
