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)`

Explanation

To solve the problem step by step, we will analyze the motion of the body under constant acceleration and derive the expression for power delivered to it at time \( t \).

### Step 1: Understand the motion of the body
The body starts from rest and moves with constant acceleration \( a \). The initial velocity \( u = 0 \).

### Step 2: Use the equation of motion to find velocity
The equation of motion gives us the velocity \( v \) at time \( t \):
