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

To solve the problem, we need to analyze the relationship between power, force, and velocity for a body in one-dimensional motion with constant acceleration.

### Step-by-Step Solution:

1. **Understanding the Initial Conditions**:
The body is initially at rest, which means its initial velocity (u) is 0.

2. **Using the Equation of Motion**:
...
