A body is initially at rest. It undergoes one-dimensional motion with constant acceleration. The power delivered to it at time t is proportional to (i) `t^(1//2)` (ii) t (iii) `t^(3//2)` (iv) `t^(2)`

Options

A. `t^((1)/(2))`
B. `t`
C. `t^((2)/(3))`
D. `t^(2)`

Answer

B

Explanation

`F = ma = "constant"`, `a = (dv)/(dt) = "constant"`
`P = Fv` and `v = u +at`
