A particle is moving along x-axis with acceleration `a=a_(0)(1-t//T)` where `a_(0)` and T are constants. The particle at t=0 has zero velocity. Calculate the average velocity between t=0 and the instant when a=0

Explanation

To solve the problem step by step, we will follow the approach outlined in the video transcript.

### Step 1: Write down the expression for acceleration
The acceleration of the particle is given by:
\[ a = a_0 \left(1 - \frac{t}{T}\right) \]
where \(a_0\) and \(T\) are constants.
