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^(3//3)`
D. `t^(2)`

Explanation

ii) from v=u+at
v=0 +at=at
`therefore p=(ma)xat = ma^(2)t`
since m and a are constants, therefore, pat.
