A particle of mass m moves on a straight line with its velocity varying with the distance travelled according to the equation `v=asqrtx`, where a is a constant. Find the total work done by all the forces during a displacement from `x=0 to x=d`.

Explanation

To solve the problem, we need to find the total work done by all forces on a particle of mass \( m \) as it moves from \( x = 0 \) to \( x = d \) with a velocity given by the equation \( v = a \sqrt{x} \).

### Step-by-Step Solution:

1. **Identify the Initial and Final Velocities:**
- At \( x = 0 \):
\[
v_i = a \sqrt{0} = 0
