A machine is delivering constant power to drive a body along a straight line. What is the relation between the distance travelled by the body against time ?

Options

A. `t^(3//4)`
B. `t^(3//2)`
C. `sqrt(t)`
D. t

Answer

B

Explanation

`P = W/t = (FS)/t`
`=(maS)/t`
`P = m/t.S/(t^(2)) S`
`kS^(2) = t^(3) rArr S prop t^(3//2)`
